I have recently upgrade to Solidworks 2010 SP 4.0. Now when I open Solidworks I get a splash screen and the nothing. Solidworks.exe appears in the task manager and then dissapears. I have uninstalled Solidworks and tried to re-install SP3.1 and now I receive the following error
"The Installation Manager encountered an error when creating this registry key: Class. You must have administrative permission when running the Installation Manager. Check the permissions for this registry key using a registry editor or consult the system administrator."
I do have administrator privelages on this machine and I have had no issues in the past. Any ideas???????
