force installation for AutoCAD Architecture 2009 from image ?

[fredrik.nilsson]

My NLS  AutoCAD Architecture 2009 64 went bonkers and locked up. I could not repair or reinstall from the control panel (it locked then too) so I removed it manually, cleaning out files and registry. takin this seriously and following advice in the Autodesk support document, I in fact I removed 16 Autodesk applications (the other 15 I could remove the "propper" way) and clean the drive and registry.

Now I can not reinstall the  AutoCAD Architecture 2009 64 as it says it is already there, which it is not.

I must have missed a key in the registry.

So I either need a pointer to the key that indicates the software to be installed OR a switch to force the installer to install from the image regardless of software present or not (I seem to recall such a possibility).

Please help!
