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?
