Summary :
The SAP Note addresses an issue where the Internet Graphics Server (IGS) fails to start on Windows due to the absence of defined "tmp" or "temp" environment variables. This results in an IGSWD tracefile error "IGS:[watchdog_main] Unknown exception". The prerequisite for this issue is an IGS installation on a Windows platform without proper environment variable setup for temporary directories. To resolve this, users must set the "tmp" and/or "temp" environment variables to a valid directory to enable IGS startup.
