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
