Windows 8 Support for AutoCAD
We're starting to receive more and more CERs (Customer Error Reports) related to crashes caused by trying to run AutoCAD on Windows® 8.
At this time, Windows® 8 and the Windows® 8 Consumer Preview are not supported operating systems for any AutoCAD versions. The AutoCAD team is actively investigating compatibility with these new platforms but, as of today, they are not currently supported.
For more information on supported operating systems refer to the solution, Operating system compatibility for AutoCAD and AutoCAD LT.
