I want to create a setup file for a web application which should be compatible with Windows 7 64 bit and MS Office 2010 32 bit.Is there any solution or fix so that the set up file is compatible with Windows 7 64 bit and MS Office 2010 32 bit.
Right now its working with Windows 7 32 bit and Office 2010 32 bit.

Set up file for what?  Your application?  If you compile your application to 32 bit, Windows 7 64 bit will still run it.
