Hi. I've a problem. Recently i tried to install Autocad Architecture 2013 on my window 7 64bit. unfortunately during the installation, for a mysterius thing, the installation crash with a message error, and then the installation it was aborted. I tried again, but right now, the setup wizard call me that autocad architecture 2013 it's already installed on my pc ! So i followed the steps shown in this page http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=2887771&linkID=9240617
I even delete all file and registry voices of autodesk products that not show in the link that i've post. afterwards i tried again to install it, but the same message appear again. Someone have the same problem ? can i resolve this, without format my pc ?
