I have upgraded the installers for both the HVAC and Electrical programs so that they now support AutoCAD 2006. All of the changes to profiles and menus in AutoCAD 2006 took a little bit longer than I expected to work out. Both of these files are available from the Design Master Files and Downloads page.
The installers will automatically detect your AutoCAD version for you and install the necessary files. When installing an updated version of Design Master, you should always install it to the same location as your previous install of Design Master. It will not overwrite any of the customization you will have done. Instead, it will be able to use all of the changes you have made.
