Change the reported OS version of Win 7 to Vista

I have a Windows 7 machine that I need to install a piece of software on that uses a “system verifier” to check to see if all prerequisites are met. It fails on the OS check since it doesn’t know version 6.1.

This software installs fine on Vista with a reported OS version of 6.0. I have no doubts that it will run without issue on Win 7 as I’ve tested all the database components between the client and server. However, the manufactures of the software say we must wait until they release a version that is “compatible” with 7 before they will allow the verifier to install and run the software.

So my question is: Is there a way to edit Windows 7 so that it reports that it is version 6.0?
