The installer cheerfully removed the previous version of the tools, then failed with a message that it could not install the SVGA driver. There's a quick message about my needing to install manually, then the system resets back to a cold boot. When restarted, I have no installed tools. Repeat, rinse...
Any way to recover back to the previous level? It was showing me the little yellow "..need to update" icon, but at least it was working.
