A number of our algorithms and environments use the Windows TEMP directory to store files. This location can be changed following the steps below. Make sure you have read and write permissions to the new location.
On Windows, you can set the TEMP environment variable in the Control Panel > System > Advanced System Settings > Environment Variables...
You can set the TEMP variable in either the system or user section (system variables will override the user variables).
If you only want to change the TEMP directory for Geomatica, you can do this in a Command Window:
C:\>set (lists all environment variables) ......
You then need to launch Geomatica from this window:
C:\>cd C:\PCI Geomatics\Geomatica_2015\exe
