To update Fax Agent, you must uninstall and reinstall in your environment. For more information on installing Fax Agent, refer to the Perceptive Content Interact for Fax Agent Installation Guide.
When you update Fax Agent from a previous version, ensure you back up the btcall.cfg file and the callctrl.cfg file located in the inserver\brooktrout\config directory. Place these files in a temporary directory away from the inserver directory. Run the installer according to the steps in the Fax Agent Installation and Setup Guide. If the CFG files are missing, replace them with the files you backed up and place them in the inserver\brooktrout\config directory.
