Thanks for posting in Microsoft TechNet Forum.
What is the name of application?
Generally, Windows Compatibility Center is coming soon. Windows 7 is engineered to be compatible with Windows Vista products, you can be assured that thousands of popular products will work with Windows 7. To verify whether the application is compatible with Windows 7, you need to contact software manufacturer for information.
