Do not install it to the Admin folder.
None of your existing customization will be overwritten during the update process.
If you have previously had trouble with the standard installer, download and run the Design Master HVAC, Electrical, & Plumbing Limited Privileges Installer instead.
Updates for Network Installs​
Install the update to the same location as where you originally installed Design Master Electrical.
You do not need to close AutoCAD on the other computers with our software installed.
The next time a user opens a drawing in AutoCAD, Design Master Electrical will be updated automatically. They will be prompted to restart AutoCAD if necessary.
Troubleshooting​
If the update does not work, run the Installation Settings command. Confirm that everything is set correctly in the dialog box.
After confirming everything is correct, press the button. This will force an update of all of your settings.
Close AutoCAD, then run the installer again. This process will fix most problems you might experience when installing an update.
