How to crack Comsol Multiphysics 4.3 b license file by modifying DLL files?
If you still want to crack Comsol Multiphysics 4.3 b license file despite the risks and disadvantages mentioned above, you will need to have some advanced skills and tools. One possible method is to modify DLL files, which are dynamic link libraries that contain code and data used by the software or other programs. By modifying DLL files, you can change the behavior or functionality of the software or other programs.
However, modifying DLL files is not a simple or easy task. It requires a lot of knowledge and experience in assembly programming and hex code manipulation. You will also need a disassembler, which is a tool that converts executable files into assembly code that can be read and edited by humans.
Here are the steps to crack Comsol Multiphysics 4.3 b license file by modifying DLL files:
Step 1: Learn assembly programming and hex code manipulation
Assembly programming is a low-level programming language that directly controls the hardware of a computer. It uses mnemonics, which are short codes that represent instructions for the processor. Hex code manipulation is the process of changing the hexadecimal values of data or instructions in a file. Hexadecimal is a base-16 number system that uses 16 symbols: 0-9 and A-F.
You will need to learn assembly programming and hex code manipulation because you will have to understand and modify the code and data in the DLL files. You can find many online tutorials and resources to learn these skills, such as:
[Assembly Programming Tutorial]
[Hex Editing Tutorial]
[Assembly Language for x86 Processors]
Step 2: Install a disassembler
A disassembler is a tool that converts executable files into assembly code that can be read and edited by humans. You will need a disassembler to open and modify the DLL files of Comsol Multiphysics 4.3 b. There are many disassemblers available, such as:
[IDA Pro]
[OllyDbg]
[Ghidra]
You can download and install any of these disassemblers on your computer. Make sure to read the documentation and instructions on how to use them.
Step 3: Open the application you want to crack in your disassembler
The next step is to open the application you want to crack in your disassembler. In this case, you want to crack Comsol Multiphysics 4.3 b license file, so you need to open the main executable file of Comsol Multiphysics 4.3 b, which is comsol.exe. You can find this file in the installation folder of Comsol Multiphysics 4.3 b, which is usually C:\Program Files\COMSOL\COMSOL43b\Multiphysics\bin\win64\.
To open comsol.exe in your disassembler, you need to locate the file in your file explorer and drag it into your disassembler's window. Alternatively, you can use the File > Open menu option in your disassembler and browse for the file.
Once you open comsol.exe in your disassembler, you will see a lot of assembly code and data in different windows or tabs. You will also see some information about the file, such as its name, size, type, entry point, imports, exports, sections, etc.
Step 4: Find the counter function
The counter function is the function that checks or validates the license file of Comsol Multiphysics 4.3 b. It is usually located in one of the DLL files that are imported by comsol.exe. You can find these DLL files in the Imports window or tab of your disassembler.
One possible way to find the counter function is to look for DLL files that have names related to licensing or activation, such as lic.dll, act.dll, licman.dll, etc. Another possible way is to look for DLL files that have functions with names related to licensing or activation, such as CheckLicense, ValidateLicense, ActivateLicense, etc.
For example, let's say you find a DLL file called lic.dll that has a function called CheckLicense. You can double-click on this function name in the Imports window or tab of your disassembler to go to its definition in the assembly code window or tab.
Step 5: Set a break-point on the counter
A break-point is a point in the code where the execution of the program stops and allows you to examine or modify its state. You can set a break-point on the counter function by right-clicking on its first instruction in the assembly code window or tab of your dis assembler and selecting Breakpoint > Toggle or pressing F2. This will mark the instruction with a red dot and indicate that a break-point is set.
Setting a break-point on the counter function will allow you to run the program until it reaches the counter function and then stop. This way, you can see what the counter function does and how it affects the program's behavior.
Step 6: Change the counter code
The next step is to change the counter code to make it always return a positive or valid result, regardless of the license file. This will trick the program into thinking that the license file is always valid and bypass the license check or validation.
To change the counter code, you need to edit the assembly code or hex code of the counter function in your disassembler. You can use the Edit > Patch menu option in your disassembler to modify the code. You can also use the hex editor window or tab of your disassembler to modify the hex code directly.
The exact way to change the counter code depends on the specific logic and structure of the counter function. You may need to analyze and understand the code carefully before making any changes. You may also need to use some common techniques or tricks, such as:
NOPing: Replacing an instruction with a NOP (no operation) instruction, which does nothing and skips to the next instruction. This can be used to remove or disable an unwanted instruction.
JMPing: Replacing an instruction with a JMP (jump) instruction, which transfers the control flow to another location in the code. This can be used to skip or redirect an unwanted instruction.
Changing operands: Changing the values or registers used by an instruction, which affects its outcome or result. This can be used to alter or manipulate an unwanted instruction.
For example, let's say you find an instruction in the counter function that compares the license file with a hard-coded value and sets a flag based on the result. The flag is then used by another instruction to determine whether to continue or terminate the program. The instruction looks like this:
cmp eax, 12345678h ; compare license file with hard-coded value jne exit ; jump to exit if not equal
You can change this instruction by NOPing it, JMPing it, or changing its operand, such as:
nop ; do nothing nop ; do nothing ; or jmp continue ; jump to continue regardless of comparison ; or cmp eax, eax ; compare license file with itself jne exit ; jump to exit if not equal
Any of these changes will make the counter function always return a positive or valid result and bypass the license check or validation.
Step 7: Recompile your newly-cracked software
The final step is to recompile your newly-cracked software and save it as a new executable file. You can use the File > Save menu option in your disassembler to save your modified DLL file. You can also use the File > Save As menu option in your disassembler to save your modified comsol.exe file as a new file.
Once you save your newly-cracked software, you can run it without any license checks or validations. You have successfully cracked Comsol Multiphysics 4.3 b license file by modifying DLL files.
