Can I double check that this was a fresh install and not an upgrade? I am guessing it was a fresh install as it's Windows 7. I have performed a few test installs on Windows 7 and although it does specify Program Files as the installation folder it does actually install into Program Files (x86) successfully. What user was the Toolbelt installer being run as? A user in the Administrator group or the actual Administrator?
