For the most part the SolidWorks uses 3 locations in the registry:
- HKEY_CURRENT_USER\Software\Solidworks\Applications\PDMWorks Enterprise
- HKEY_LOCAL_MACHINE\SOFTWARE\SolidWorks\Applications\PDMWorks Enterprise
- HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SolidWorks\Applications\PDMWorks Enterprise
The first location is specific to your account on the machine and usually has to do with what is shown in the Administration tool. There are a huge number of other places where SolidWorks information is stored in the registry, so it would be hard to say exactly where it is looking.
