I tried to run a service pack and received the 'cannot ascertain the version' error. DUInstall said the current version couldn't update to the one I was trying to install. I realized my error and tried to apply the correct service pack. It still thinks I'm trying to update to the incorrect one. Is there a way around this rather than to restore a backup? I was stupid and didn't take my own backup and they are trying to track down the IT guys at the client to get the backup.
Backup does not fix the issue.
I am able to access this on client machines so will uninstall from the server and just reinstall the client. Hopefully that will work as I'm not sure how I can update otherwise.
