Upgrading to VS2008 Question

[jersey]

I have VS2005 Professional. I am unable to install it on my new Vista 64-
bit computer. The only reason I wanted to install it was to be able to
purchase and install VS2008 Upgrade version. If I purchase VS2008 Upgrade
(rather than the full non-upgrade version), will I be able to install it
or will I be told no copy of Visual Studio can be found to upgrade? Is
there any solution to this problem?

TIA

I believe there is an issue involving office 2007 and/or silverlight.
Try uninstalling both of these (if they are installed) and then try
installing vs2005.
