When installing FogBugz, you may receive the following error message:

DISM.exe or ‘net’ is not found. 

While this is not an issue related to the product, it prevents the installation from being completed. This article provides information on the resolution of this issue. 

Root Cause

   C:\Windows;

   If you prefer to use the Edit text option, make sure that variables are separated by a semicolon.
