We were upgrading from 6.12 to 7.0 on our production server. The upgrade simulation went through with flying colors. When continuing with the install we got the 3 errors shown on the 1st. page of the attachment. Continued on and all seemed good. However when trying to open Workflow or Configuration we got the error shown on the 2nd page of the attachment. And when trying to open DW through the web apps in the Task Bar we got the error shown on page 3. Now going to DW through IE by entering the web address opened DW it seemed to work fine. It seems that anything related to Desktop Apps refuses to work.
We did backup the DB and since the DW server is a virtual, we also backed that up so we were able to restore everything back to its original working condition. Just wanted to see if anyone else has run into a situation like this before we try it again.
