I obtained Microsoft Officew Professional Plus 2010 for home use via the Home Use Program. I have Windows 7 Home Premium 64 bit. When I try loading Office I get the following error message:
Error 1920. Service 'Office Software Protection Platform' (osppsvc) failed to start. Verify that you have sufficient privileges to start system services.
I have administrator privileges on my computer. So I need help resolving this issue.
