It is not supported of course, but since Vista is locked down and shipping, is there a workaround to install Beta 2 of XNA GSE on Vista
Repro steps:
- On Vista RTM
- Install C# Express
- Launch XNA GSE Beta 2
- When it is "registering templates", an error message about C# Express closing down appears
- XNA GSE Installation app errors as well, saying that something went wrong
- Installer reverses all the installation...

Workaround to make XNA GSE work on Vista RTM?

I know that some people have gotten the GSE and XNA Framework to work under Vista...
Remember that the GSE and XNA System is unsupported under the Vista system, in future releases this should be fixed when the updates to the Express Products are released.

Yes, as always, Vista is not supported on vista in any way right now.
Anyways, to get it to work you could either run from an elevated command prompt, or what I neglected to mention, create a shortcut to the MSI, which will allow you to run as Administrator. Also note the the Visual Studio Express service pack you must install is a Beta product, but you should be comfortable with that by now :)
So far I have had no problems with Vista and XNA (Beta 2) - Good luck!

Of course, after installing the SP for C#

.msi installation packages don't have the "Run as Administrator" options. I did try to run it while logged in as the main Administrator user name, which should be the same thing (not working).
I was able to work around issues in Vista RC1, but it is another story with Vista RTM.
I believe that C# Express has been updated and now includes the Service Pack bits by default
