Installing connector 6.3.5 on Windows 7 64 bit (no replies)

I have looked all over the internet, and cannot find an answer. Sorry if it is simple.

I have downloaded the latest 6.3.5 MSI file. When I attempt to install it, it progresses about halfway through, then begins a rollback and fails to install. Is there any way to find what failed, or is there a known problem that I can work around?

My environment is Windows 7, 64 bit; Visual Studio 2008. I downloaded the MSI version from the MySQL web site.

Thanks,

Don
