Deployed Application occmgr.cpp Assert Failure

[Graham]

I have developed a Simple MFC GUI to allow a user to display and control an activity
The program works fine on a PC with Visual Studio installed, but when I transfer the progra
to a Laptop computer I get an Assertion Failure line 410 of file occmgr.cpp

I built a Deployment & Install project to formally install the program, but still keep getting the same error. It works fine on a desktop PC without Visual Studio installed

Someone suggested to try ( from Microsoft).
