It cannot be installed on 64-bit Windows” Installing AutoCAD LT 2012 32bit on Windows 7, Windows 8, Windows 8.1 or Windows 10 64bit can be very easily defined in these short steps NOTE: These steps do not bypass normal Autodesk licensing/authorization, you should expect to use your own serial numbers in the normal way.
