As das_stig suggested, more information would be helpful here. When are you seeing the message? Are you trying to upgrade from Vista or XP to Windows 7 (or, did you just perform an upgrade)? Have you tried using Windows Updates to update your drivers?
Hope this helps!

Just an FYI for you.
It is always best to check with the software manufacturer FIRST. They will tell you if they have tested the product and the version, as well as whether or not it will work with Windows 7.
Check out the Windows 7 Compatibility site: (There you will find out about hardware and software compatibilty.) http://www.microsoft.com/windows/compatibility/en-us/de...
There is a pulldown from which you can choose "hardware" and "software".
There are also some great articles, instructional videos and such to help with your Windows 7 at our Springboard site: http://technet.microsoft.com/en-us/windows/default.aspx
In any event a lot of the times, Vista drivers will work in lieu of Windows 7 drivers, however, it's not 100%!
As stated previously, it's best to have the Windows 7 certified drivers installed.
Microsoft does have an official Windows 7 Support Forum located here http://tinyurl.com/9fhdl5 . It is supported by product specialists as well as engineers and support teams. You may want to check the threads available there for additional assitance and support.
