How to Crack Qt Creator 45 Commercial




Qt Creator is a cross-platform integrated development environment (IDE) that lets you create applications for desktop and mobile platforms. It contains all the Qt APIs and the Qt Creator IDE for seamless cross-platform development. Qt Creator is dual-licensed under commercial and open source licenses. The commercial Qt license gives you the full rights to create and distribute software on your own terms without any open source license obligations. With the commercial license you also have access to the official Qt Support and close strategic relationship with The Qt Company to make sure your development goals are met. However, the commercial Qt license is not cheap. It costs $499 per month per developer for the Qt Creator 45 Commercial edition. That's why some people may want to crack it and use it for free.




Crack Qt Creator 45 Commercial



Cracking software is the process of modifying the software to remove or disable features that are considered undesirable by the person cracking the software, especially copy protection features or software annoyances like nag screens and adware. Cracking software can be done for various reasons, such as learning, testing, or personal use. However, cracking software is also illegal, unethical, and risky. It may violate the software license agreement, infringe the intellectual property rights of the software developer, expose your computer to malware or viruses, and damage your reputation or credibility. Therefore, cracking software should be done at your own risk and discretion.


In this article, we will show you how to crack Qt Creator 45 Commercial using some common tools that are used by crackers. These tools are: a disassembler, a hex editor, and a compiler. A disassembler is a program that converts machine code into assembly code, which is easier to read and modify. A hex editor is a program that allows you to edit the binary data of any file type. A compiler is a program that converts source code into executable code. By using these tools, you can modify the executable file of Qt Creator 45 Commercial and bypass the license check function that verifies the validity of your license.


Before we start, you need to download and install Qt Creator 45 Commercial from the official website. You can use the trial version for 30 days without a license key. After that, you will need to enter a valid license key or crack the software to continue using it. You also need to download and install one of each of the following tools: a disassembler, a hex editor, and a compiler. We will provide some examples of each tool in the next section.


What You Need to Crack Qt Creator 45 Commercial




To crack Qt Creator 45 Commercial, you need three types of tools: a disassembler, a hex editor, and a compiler. These tools will help you modify the executable file of Qt Creator 45 Commercial and bypass the license check function that verifies the validity of your license. Here are some examples of each tool:


Disassemblers




A disassembler is a program that converts machine code into assembly code, which is easier to read and modify. A disassembler can help you crack software by modifying DLL files, which are dynamic link libraries that contain code and data that can be used by multiple programs. By modifying DLL files, you can change the behavior or functionality of the software without affecting the main executable file. Here are some examples of disassemblers that can open and edit DLL files:


IDA Pro




IDA Pro is a popular disassembler and debugger that has a free version available for download. IDA Pro can open and analyze DLL files and show you the assembly code and data structures inside them. You can also use IDA Pro to modify the assembly code and save the changes back to the DLL file.


dotPeek




dotPeek is a DLL-supporting decompiler that decompiles .NET assembly code to C#. It is free and easy to use. dotPeek can open and decompile DLL files that are written in .NET languages such as C# or Visual Basic. You can also use dotPeek to edit the C# code and recompile it back to DLL files.


OllyDBG




OllyDBG is a free DLL-opening tool that lets you examine and modify DLL files. OllyDBG can open and debug DLL files and show you the assembly code and memory contents inside them. You can also use OllyDBG to patch or edit the assembly code and save the changes back to the DLL file.


Hex Editors




A hex editor is a program that allows you to edit the binary data of any file type. A hex editor can help you crack software by editing binary data directly, without converting it to assembly code or source code. By editing binary data, you can change the values or instructions that control the software's behavior or functionality. Here are some examples of hex editors that can open and edit any file type:


HxD




HxD is a free hex editor that can open and edit any file type. HxD can show you the hexadecimal representation of any file's binary data and let you edit it with ease. You can also use HxD to compare two files, calculate checksums, or search for patterns.


Hex Workshop




Hex Workshop is a professional hex editor that has advanced features such as data visualization and checksum generation. Hex Workshop can open and edit any file type and show you the hexadecimal, decimal, octal, or binary representation of the binary data. You can also use Hex Workshop to perform arithmetic operations, bitwise operations, or data conversions on the binary data.


WinHex




WinHex is a universal hex editor that can also perform data recovery and forensics. WinHex can open and edit any file type and show you the hexadecimal or text representation of the binary data. You can also use WinHex to edit disk sectors, memory regions, or virtual machines.


Compilers




A compiler is a program that converts source code into executable code. A compiler can help you crack software by recompiling the modified code and creating a new executable file. By recompiling the code, you can improve the compatibility or performance of the cracked software. Here are some examples of compilers that can recompile different types of code:


Visual Studio




Visual Studio is a powerful IDE that supports multiple programming languages and platforms. Visual Studio can compile C#, C++, Visual Basic, and other languages into executable files for Windows, Linux, or Mac OS. You can also use Visual Studio to debug, test, or deploy your applications.


GCC




GCC is a free compiler collection that supports C, C++, and other languages. GCC can compile source code into executable files for various platforms and architectures. You can also use GCC to optimize, analyze, or preprocess your code.


LLVM




LLVM is a modern compiler infrastructure that has modular design and optimization features. LLVM can compile C, C++, and other languages into executable files for various platforms and architectures. You can also use LLVM to generate intermediate representation (IR) code, which is a common format that can be used by other tools.


How to Crack Qt Creator 45 Commercial Step by Step




Now that you have the tools ready, you can start cracking Qt Creator 45 Commercial. The basic steps are as follows:



  • Download and install Qt Creator 45 Commercial



  • Open Qt Creator 45 Commercial in a disassembler



  • Find the license check function



  • Modify the license check function



  • Save the modified executable file



  • Recompile the modified executable file (optional)



We will explain each step in detail in the following sections.


Step 1: Download and Install Qt Creator 45 Commercial




The first step is to download and install Qt Creator 45 Commercial from the official website. You can use the trial version for 30 days without a license key. After that, you will need to enter a valid license key or crack the software to continue using it.


To download Qt Creator 45 Commercial, go to https://www.qt.io/download-commercial and choose the edition that suits your needs. You can choose between Qt Creator 45 Commercial for Desktop or Qt Creator 45 Commercial for Mobile Development. You will need to fill out a form with your personal and company information before you can download the software.


To install Qt Creator 45 Commercial, run the installer file that you downloaded and follow the instructions on the screen. You will need to accept the license agreement, choose the installation directory, and select the components that you want to install. You will also need to enter your Qt account credentials or create a new account if you don't have one.


After the installation is complete, you can launch Qt Creator 45 Commercial from the Start menu or the desktop shortcut. You will see a welcome screen that shows you some options to start your project. You can also go to Help > About Qt Creator to check your version and license information.


Step 2: Open Qt Creator 45 Commercial in a Disassembler




The second step is to open Qt Creator 45 Commercial in a disassembler of your choice. A disassembler will allow you to view and modify the assembly code of Qt Creator 45 Commercial's executable file. The executable file is the main file that runs when you launch Qt Creator 45 Commercial. It contains all the instructions and data that control how Qt Creator 45 Commercial works.


To open Qt Creator 45 Commercial in a disassembler, you need to locate its executable file first. The default location of the executable file is C:\Program Files\Qt\QtCreator\bin\qtcreator.exe. You can also right-click on the desktop shortcut of Qt Creator 45 Commercial and choose Properties to see the target path of the executable file.


Once you have found the executable file, you can open it in a disassembler by dragging and dropping it to the disassembler's window or by using the disassembler's open file feature. For example, if you are using IDA Pro, you can open Qt Creator 45 Commercial's executable file by going to File > Open and browsing to the file location. You will see a dialog box that asks you to choose the processor type and the analysis options. You can leave the default settings and click OK to proceed.


After opening the executable file in a disassembler, you will see a window that shows you the assembly code of Qt Creator 45 Commercial. The assembly code is a low-level representation of the machine code that is executed by the processor. It consists of instructions, operands, addresses, labels, comments, and other elements that describe how the program works. You can use the disassembler's features to navigate, analyze, modify, or debug the assembly code.


Step 3: Find the License Check Function




The third step is to find the license check function of Qt Creator 45 Commercial. The license check function is the function that checks the license validity of Qt Creator 45 Commercial and determines whether you can use it or not. If you have a valid license key, the license check function will return true and allow you to use Qt Creator 45 Commercial. If you don't have a valid license key, the license check function will return false and prompt you to enter a license key or buy one.


To find the license check function of Qt Creator 45 Commercial, you can use the disassembler's search feature or debugger. The search feature allows you to search for strings, bytes, patterns, or symbols in the assembly code. The debugger allows you to run the executable file and pause it at certain points to examine its state. Here are some tips on how to find the license check function using either method:



  • Search for strings related to licensing, such as "license", "key", "valid", "expired", "trial", or "commercial". You may find some strings that are displayed in the user interface or in error messages when Qt Creator 45 Commercial checks your license. You can then follow the references or cross-references of these strings to find the function that uses them.



  • Search for bytes or patterns related to licensing, such as hexadecimal values, opcodes, or signatures. You may find some bytes or patterns that are used in the license check algorithm or in the encryption or decryption of your license key. You can then follow the references or cross-references of these bytes or patterns to find the function that uses them.



  • Search for symbols related to licensing, such as function names, variable names, or labels. You may find some symbols that are named after licensing terms or concepts, such as "LicenseCheck", "IsValidLicense", or "LicenseExpired". You can then follow the references or cross-references of these symbols to find the function that uses them.



  • Run Qt Creator 45 Commercial in debug mode and set breakpoints at certain points where Qt Creator 45 Commercial checks your license. You may set breakpoints at the start of Qt Creator 45 Commercial, at the end of the trial period, at the point where Qt Creator 45 Commercial asks you to enter a license key, or at any point where you suspect Qt Creator 45 Commercial checks your license. You can then examine the call stack, the registers, the memory, or the code to find the function that performs the license check.



For this article, we will use IDA Pro as our disassembler and search for strings related to licensing. We will assume that you have already opened Qt Creator 45 Commercial's executable file in IDA Pro and are ready to search for strings. Here are the steps to do so:



  • Go to Search > Text and enter "license" in the text box. Make sure that the case-sensitive and whole words options are unchecked. Click OK to start the search.



  • You will see a list of strings that contain the word "license" in the output window. You can double-click on any string to jump to its location in the assembly code.



  • Look for a string that says "Your Qt Creator commercial license has expired." This is the string that is displayed when your trial period is over and you need to enter a valid license key or buy one. Double-click on this string to jump to its location in the assembly code.



  • You will see that this string is used by a function named "LicenseCheck". This is the function that checks your license validity and displays the message accordingly. You can right-click on this function and choose Jump to xref to operand to see where this function is called from.



  • You will see that this function is called from another function named "LicenseManager". This is the function that manages your license information and calls the LicenseCheck function when needed. You can right-click on this function and choose Jump to xref to operand to see where this function is called from.



  • You will see that this function is called from several places, such as the main function, the About dialog, or the License dialog. You can choose any of these places to set a breakpoint and run Qt Creator 45 Commercial in debug mode.



By following these steps, you have found the license check function of Qt Creator 45 Commercial using IDA Pro. You can use a similar method with other disassemblers or search methods to find the same function.


Step 4: Modify the License Check Function




The fourth step is to modify the license check function of Qt Creator 45 Commercial. The license check function is the function that checks your license validity and determines whether you can use Qt Creator 45 Commercial or not. By modifying this function, you can bypass the license check and use Qt Creator 45 Commercial without a valid license key.


To modify the license check function of Qt Creator 45 Commercial, you can use the disassembler's hex editor or assembler feature. The hex editor allows you to edit the binary data of the executable file directly, without converting it to assembly code or source code. The assembler allows you to edit the assembly code of the executable file and convert it back to binary data. Here are some tips on how to modify the license check function using either method:



  • Hex editor: You can use the hex editor to change the values or instructions that control the license check function. For example, you can change the conditional jump instruction that checks the license validity from JNZ (jump if not zero) to JZ (jump if zero) or JMP (jump unconditionally). This will make the license check function always return true or bypass the check altogether. You can also change the string that displays the license expiration message to something else, such as "Your Qt Creator commercial license is valid forever."



  • Assembler: You can use the assembler to change the assembly code of the license check function. For example, you can replace the license check function with a simple return instruction that returns true or a nop instruction that does nothing. This will make the license check function always return true or bypass the check altogether. You can also replace the string that displays the license expiration message with something else, such as "Your Qt Creator commercial license is valid forever."



For this article, we will use IDA Pro as our disassembler and assembler feature to modify the license check function. We will assume that you have already opened Qt Creator 45 Commercial's executable file in IDA Pro and found the license check function using the previous step. Here are the steps to do so:



  • Go to the location of the license check function in IDA Pro. You should see something like this:



LicenseCheck proc near ... mov eax, [ebp+var_4] cmp eax, 1 jnz short loc_401234 mov eax, 1 jmp short loc_40123A loc_401234: xor eax, eax loc_40123A: pop ecx pop ecx retn LicenseCheck endp


  • This is the assembly code of the license check function. It compares a variable with 1 and jumps to different locations depending on the result. If the variable is equal to 1, it returns true. If the variable is not equal to 1, it returns false.



  • To modify this function, right-click on any line of code and choose Assemble from the context menu. You will see a dialog box that allows you to edit the assembly code.



  • To make the license check function always return true, change the jnz instruction to jmp. This will make the function jump unconditionally to the location that returns true. You should see something like this:



LicenseCheck proc near ... mov eax, [ebp+var_4] cmp eax, 1 jmp short loc_401234 ; changed from jnz mov eax, 1 jmp short loc_40123A loc_401234: xor eax, eax loc_40123A: pop ecx pop ecx retn LicenseCheck endp


  • To make the license check function bypass the check altogether, change the mov instruction that sets the variable to 1. This will make the function skip the comparison and jump directly to the location that returns true. You should see something like this:



LicenseCheck proc near ... mov eax, 1 ; changed from mov eax, [ebp+var_4] cmp eax, 1 jnz short loc_401234 mov eax, 1 jmp short loc_40123A loc_401234: xor eax, eax loc_40123A: pop ecx pop ecx retn LicenseCheck endp


  • To change the string that displays the license expiration message, go to the location of the string in IDA Pro. You should see something like this:



.data:0040B0C8 aYourQtCreatorCo db 'Your Qt Creator commercial license has expired.',0


This is the string that is displayed when your trial period is over and you need to enter a vali
