When upgrading TotalAgility from 7.8.0 R2 to 18.104.22.168, applying any fix packs earlier than 22.214.171.124 on 7.8.0 R2 resulted in incorrect working environment and jobs were suspended on extraction with the following error: " Error occurred while executing script or method. Could not load file or assembly Atalasoft.Shared...."
This is a known issue as documented on page 42 of the KTA 7.8 Release Notes.
Apply fix pack TotalAgility 126.96.36.199 or later.
Fix Pack 188.8.131.52 and above can be directly applied against any previous version of the 7.8.0.R2 fix pack without any need to uninstall or revert the current fix pack version.
