Error Adding File (The operation being requested was not performed because the user has not logged on to the new.ork. The specified service does not exist. (Exception from RESULT: Ox800704DD)).
I upgraded a small charity’s Sage installation recently and got the above error on two out of three machine. After the upgrade completed the update dialog appeared but it failed with the above error. One the one machine the update process installed (Service Pack 4) successfully.
On the other two machines, a bit later I just reopened and closed Sage, then the update re-ran and was successful on both PCs.
