So I'm looking for a method to close a handle of this exe, it is a mutex and it stops you from having more than 1 of the same application (obviously) so if I use procex I can close the handle by going to mutant and choosing the mutex, so I need some pointers...
Are you trying to bypass the mutex check so you can have more than one instance of an application? To the best of my knowledge it cannot be done. The mutex is open (and probably acquired) in the process and cannot be meddled with. But then again, I don't do this type of rogue programming.
