[2005] App starts correctly in user it was installed in, but not other

A while ago, I discovered if you move or delete any of the files installed by my setup project (from the install directory), that when you open the program, it starts the uninstaller (which makes sense, to repair itself)...

Now the problem I am having is when my application is installed, when I start windows in a different account, say I installed on Icyculyr, which has administrator priveliges (haha I can't spell), if I start windows in 'Administrator', which is the default account for windows, or another user, it starts the uninstaller like my files were moved...

I am quite confused about this..

Any idea's?

I have clarified the above post, please if anyone has any idea's, please reply..

Thanks
