How do I modify the installation of the 2012 products as I am trying to install the Express Tools options for AutoCAD Electrical?
The 2012 products are modified by going through Control Panel. Depending on which version of Windows you are using you will be able to modify your installation.
EG Windows 7 > Programs & features > Right Click on AutoCAD Electrical > Uninstall / Change
From here you can select the Express Tools."
