When an error occurs in the Publisher, a log file (.log) is created in the following places, depending on your operating system:

Basic log files:

C:\Users\username\AppData\Local\EsriUK\InstantAtlas\ia{x}.log

Advanced log files:

C:\Users\username\AppData\Local\Temp\ia_stderr.log

Where username is your username and {x} is a numeral. There may be multiple log files in these folders. Check the date and time of creation to identify the one you require. You can open a log file using any text editor (e.g. Notepad). When contacting the support team for troubleshooting, please include these error messages as they can help your support provider resolve problems quickly.
