AutoCAD 2013 will not install for me on a LenovoT430si laptop runninng WIndows XP Pro. The regular Auodesk Install procedure goes most of the way, but then a Windows Installer display opens giving information about msiexec options, but there is only an OK button on this display. When I try the installation using the command line and msiexec /i, I am not entering the correct sequence to allow the installation from the USB drive, e.g. msiexec /i G:\x86\acad\acad.msi. I also would like to install Inventor and Revit on this same laptop. Can anyone tell me how to accomplish the installation of these Autodesk 2013 packages?
