You may not want to install 'Cooper' from Autodesk on a machine that has AutoCAD LT, (I don't know about other versions).
I installed Cooper on my machine just to check it out, and it hosed my 'Properties' box within my LT. The properties box would appear, but it was empty. No cells / text.
I tried several things to get it back and was only a couple of steps away from re-intalling my CAD, (after an hour or so of trying to fix it), then all of a sudden CAD started working fine again.
I didn't see any benefit to Cooper, and was disappointed that it wouldn't open any of my CAD files - even though it does use the .dwg extention.
Admittedly, I don't know Autodesk's targeted customers.
