Can't repair subscription center install of AuotCAD 2012

[Ghostship]

I have the problem where the properties palatte isn't working.  If I grip an object the drop down of selected objects show blank, and not the default "no selection".

Popular opinion seems to be to do a repair install.

I'm currently installed with 64bit on windows 7.

If I re-run the executable and type in my serial and key, I get "installed" with no option to repair.

If I try to go throuhg control panel, the uninstall/change button does nothing.  It works for other Autodesk products, but not AutoCAD. 

How can I do a repair?

You might just have to remove it altogether and put it back on fresh.

For more information on the Autodesk KB Support article concerning the clean uninstall of Autdoesk products, see this link:

For all other installation problems on Windows XP SP2 or below consider using the Microsoft Installer Clean Up Utility. For more information on this program, please my forum post here:
