Workaround
Warning: Ensure you have a full recent Archive Manager SQL database backup before running any of the below SQL queries.
1. Delete the "Source Property Config" value from the Config table using the following SQL script:
delete from config where "key" = 'Source Property Config'
2. Reset the version number so the Installer will re-update the Database and fix the issue. Delete all the versions from 4.1.0.82 onwards (Including the 4.1.0.82 entry) using the following SQL script:
delete from version where version > '4.1.0.87'
3. Run the ArchiveManager installer and upgrade the database again, then quit the installer.
