I have repeatedly tried to install MS Office 2010 beta. I always get the following error: Error 1920 Osppsvc The service could not be started. Make sure you have sufficient privileges to start system services. I want to install via the admin account and using the normal account, no success. Can you tell me why I getting Error 1920 while installing MS Office 2010 beta on Windows 7 64-bit. This service, I can not find it. Maybe someone knows the solution?
