When trying to register “Microsoft.ContentManagement.Common.dll” using RegSvr32, you get this error:
The module “Microsoft.ContentManagement.Common.dll” was loaded but the entry-point DllRegisterServer was not found.
Make sure that “Microsoft.ContentManagement.Common.dll” is a valid DLL or OCX file and then try again.
This is because there are some files needed for WSS that need to be copied over to your installation.
