Windows TS mem err running certain user

I am having trouble running a program as a certain user. This program can be run by other users with no problem, this program can be run by the user that is having problems if they choose run as different user from the shortcut and change users. The error that I am getting is:

The instruction at “0x6c6f70a6” referenced memory at “0x00000058”. The memory could not be written.

Is there some way that I can force the user and that program into a different memory space? Any help is greatlyappreciated.
