Chimp Rewriter runs on Windows using the Dot Net 4 framework. It therefore runs on all versions of Windows from Windows XP up to Windows 8. However, we are reluctant to support Windows Vista as this Operating System causes more problems than it is worth.

We also support Windows 8 if you wish to downgrade to it. 

We specifically test Chimp Rewriter on Windows XP, Windows 7 and Windows 8 before each release.
