Vista - Opening Multiple windows of the same game

I am trying to open more than one window of the same game, however I have
been unsuccessful in doing so.

I have attempted to 'Run As', but the only option is 'Run as administrator'.
I have administrative rights under this account, and even when I removed
those powers the option remained.

I also created multiple profiles, some administrators, some standard
accounts; some with passwords, and some without.

I was still unable to get anything else to show up under 'Run As'.

I even reinstalled the game in another location and renamed the exe file,
but it still will not open.


Any suggestions?

You may be able to open task manager, and find the .exe of the game, right click it and change the affinity. This will make it run on a different core. Not sure if this will allow you to play it in a second window, but it's worth a shot.
