Im using Tabs3 with PracticeMaster, General Ledger, Accounts Payable and Trust Accounting software. Do I need to put them all in the same directory?

Yes, this is required if you want the software to integrate. When integrating with other Tabs3 and PracticeMaster software applications, all of the applications’ program files must reside in the same directory as the System Configuration program files for integration and integrated file locking to work.
