When trying to run a Data Protection for SQL command, the following message is received: ACO0004E An unknown error has been detected.

For example:

Or, from within the TDP for SQL GUI:










This error can occur when the base-level TSM BA client is upgraded to a newer version. In certain situations, the TSM API runtime files get out of sync. This issue was solved by (un)installing all the TSM components in this order:

1. Uninstall Data Protection for SQL.
2. Uninstall the base-level TSM BA client.
3. Reinstall the base-level TSM BA client.
4. Reinstall Data Protection for SQL.
5. Retry the operation.
