Why does Tally Prime suddenly open in Educational Mode?

Tally Prime reverts to Educational Mode if: (1) The License Server service is stopped on the host machine. (2) Windows Firewall is blocking Port 9000/9999. (3) Your Tally Software Services (TSS) or rental license has expired. (4) System IP changed or hardware was updated without reactivating the license.

How to reactivate an existing Tally Prime license on the server?

Open Tally Prime as Administrator. On the startup screen, select 'Reactivate Existing License' (or press F1 > Settings > License > Reactivate). Enter your registered Tally.NET ID and password. Tally fetches and installs the license file automatically.

How do I connect a client machine to the Tally License Server on LAN?

On the client machine: Open Tally Prime > F1: Help > Settings > License > Manage License > Use License from Network. Enter the Server's IP address (e.g. 192.168.1.100) and Port 9000. Ensure Port 9000 is open in Windows Firewall on the server.

Does TrulyInvoice work when Tally Prime is in Educational Mode?

Educational Mode restricts Tally from entering vouchers on dates other than the 1st, 2nd, and 31st of the month. To sync purchase vouchers on all dates via TrulyInvoice's Port 9000 connector, Tally Prime must be running in a fully licensed mode.

How do I prevent Windows Firewall from blocking the Tally License Server?

Create an Inbound Rule in Windows Defender Firewall for TCP Port 9000 and 9999, and add an application exception for 'tally.exe' and 'tallygatewayserver.exe' located in your TallyPrime directory.
