Installed the update 6.0.12092 then ran the tools installer using my admin id. It got all of the way through, failed at the end, then backed out. Parallels reports that tools need to be installed. Now when I try to start the tools installer, nothing happens. Followed the purge of tools from the registry etc. by following article ID: 8969 and still no joy. Done the usual reboot, etc and no joy. Any ideas?
