Tally cannot start as required file (tally.dif) is missing or corrupted

Cause

This error appears when the tally.dif file is deleted from the capsules folder, and the absence of a stable internet connection prevents the update of this file.

Solution

Ensure that your computer is connected to the internet, so that the tally.dif file can be updated. Alternatively, re-install Tally.ERP 9.
