Best way to run 2 instances of an app on a Windows 7 computer

Hello Folks,

I have a client with about 10 workstations that needs to run two instances of a database front end app on each of their computers. The application is not engineered to run two instances at once so I am thinking the best way to approach this might be with some kind if virtulization solution. Could you folks give me some advise on the simpliest and most economical way to approach this problem?

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If the app will operate under Windows XP then I'd go for XP Mode as the easiest option.
