I need to re write exe file and remove limit from it. it actually have a limit when program is running and it is closing or not working after limit is reached. and I have to close and open again. Now I want to remove this limit from exe, and it will continue running.... I think somebody who knows assembly and good at reverse engineering then you will just change asm code, I think few lines of code where it compare values, it must be removed and software will continue working.
