Installing AutoCAD Architecture 2011 32bit on Windows 7, Windows 8, Windows 8.1 or Windows 10 64bit can be very easily defined in these short steps…

  1. Obtain your copy of the Longbow Converter tool here

    2. Wait until all of the files have extracted, when they do, note that the ADT 2011 setup will automatically launch – make sure you close the setup and move to the next step.
    3. Now, start the Longbow Converter tool, select the 1st tab named “AutoCAD 32bit Installer Converter
    4. Next, using the ‘‘ button select the newly created c:\Autodesk\ADT2012 folder
  5. Next, in the Converter App, click the ‘Convert‘ button
    1. Once the conversion process is complete, simply click the “Install/Run Setup to start the setup.
    2. Now, just install as normal.

      3. then click the ‘Fix‘ button.
