i play a game that only allows me to open one instance of the game at a time. is there anyway to get round this without a vm or another windows user acc

Try to open the process with Sandboxie, or change the process name (:

Debug the application and locate what causes it to be detected to have multiple instances.

A lot of applications use mutex threads to only allow one instance of the application to run at a time. You can remove the check / creation of the mutex (if it is using that method) and you should be good to go.

You can look for calls to CreateMutex / CreateMutexEx for this method.

There are plenty of other methods that can be used, but this is usually the most common one you will see.

If this is mplestory or a similar game, you need a virtual pc.

hex edit, or view it in olly (make sure it's not packed or encrypted) and then search for the window name, or the process name. And simply remove the check for it in olly (or rename it), if renamed it'll fail the comparison with the window name and it will let you run multiple instances of it.
