Windows 7 and DOS programs

A few computers with WinXP works at my small office.
These computers, shares an old DOS application (classic Clipper+dBase).

Unfortunately lately I had to replace one of WinXP with Windows 7 and the problems begins as DOS program wont work under Win7.

DOSbox is not an option here as it is shared application. Modifying shared files with dosbox is a bad idea. It overwrites data and mess up. Already tested .

So in this situation I want to ask anyone of you: do you have any workaround to start DOS program with Windows 7 ?

You could run a Windows XP VM on the Windows 7 machine, only suggestion I can think of without using DOSBox and messing with your data.

Thanks for this reply.
I was thinking of VM (VirtualPC/VirtualBox) as well. However it requires Windows XP license/Box version. Now a days it is impossible to buy :/ (Even Though I have already invested into a new workstation with OEM Operating System)

Are the other Windows XP machines OEMs or custom builds?

I am away now but as far as I remember it is Professional version.
If so, I am very curious about that Windows XP Mode and Virtual PC.

As soon as I will be back (tonight probably), I will look at this. I assume I need to download some Windows XP image and Virtual PC. If so, that would be a very good solution.

@x BlueRobot: unfortunately, it is/was OEM.
