Unable to Migrate as one or more required application files are either corrupted or missing. Repair TallyPrime application, and try again.
Cause 1: This error occurs when the version of the Migration Tool does not match the version of the Tally client. It usually happens when you copy the Migration Tool from one version of TallyPrime and paste it into another version, causing a mismatch with the Tally client.
Cause 2: The Migration Tool is either corrupted or deleted, and therefore not present in its designated directory.
Resolutions: Repair your TallyPrime application.
- Press F1 (Help) > Troubleshooting > Repair/Re-install Application.
- Press R (Repair) and select Yes to close TallyPrime and open Setup Manager to repair the TallyPrime application.
Now, try migrating your data again.
