v2014 upgrade (from v4.3), SBS 2008 64 OS. Initial install seemed to be ok. Installed the PU 1 along with the little patches. Then I got brave and tried the new PU3. Threw an error message (missing sy_options????), then I had to remove the install lock and the errors started to cascade. So I decided to start over by deleting the MAS 90 folder and the fun really began. The few minutes that was promised for installing the prerequisites ran all night without ending. Then I thought, what the heck, the prerequisites should already exist because of the previous install so I bypassed the autorun.exe and ran the .msi program. Received the second error after keying in the administrator password.
Now I am guessing I have clutter in the registry, thought I would post here before calling Sage....
