I do have problem same I read in the forum, "You cannot install this product on the current operating system" in my SAMSUNG R590 with 64-bit OS.
Calling all user of AUTOCAD 2011 voice out your problems, send them back to Autodesk. I pressumed the 2011 release is quite confusing and experimental.
Please forward and dessiminate this testimony to everybody that 2011 is no use.
I noticed from the application and support od 2011 my graphics card is not listed as vendor of AUTOCAD/AUTODESK but it was a family of NVIDEA (GeForce GT 330M) I pressumed this wiil the cause.
I am having a similar problem installing Autocad 2011 on Windows 7 Entreprise (32-bit). The installation stalls when the Installer attempts to install the Visual c component at the beginning of the process. About 20 minutes later, the installer summary reports installation failure of all components.
Has anyone overcome a similar problem?
