I installed SolidWorks 2011 SP0 (both x32 and x64) from the disk and then did an update to SP3. During the update we would get a number of errors. We worked with our VAR and ended up with no good solutions. I then did the super secret "total uninstall" which is a hidden option and should be in the main menu. After that I did a complete install of 2011 SP3 from the downloaded files and did not get errors. The errors seem to be a product of doing updates vs. doing a new install from the latest service pack. The "total uninstall" option seems to clean up the registry also for a better install.
Has anyone else seen this issue?
