License File Installation

Your license file is sent to you after you have purchased Design Master. The file that is sent should be extracted to your Design Master folder. If you purchased both DM HVAC and DM Electrical, it should be extracted to both of their folders.

The license file is sent as a ZIP file containing two ARX files, one for AutoCAD 2000 to 2002, and the other for AutoCAD 2004 and later. Only one file is typically necessary, but it is easiest to always extract both to your Design Master folder. The extra file will not cause any problems.
