IntelliCAD 7 remains unusable even after installing the latest round of updates (build 101208). Drawing performance is pretty terrible, drawings crash when saving, changing from layout to model causes crashes pretty frequently, user profiles do not appear to be saved (toolbars constantly revert back to standard) etc etc...
If you want to installed 7 you will either need to re-install from the CD or by downloading the latest Carlson2011.exe file from theirwebsite:

Unless you have nothing to do, don't waste your time.
