Installing AutoCAD Architecture 2012 32bit on Windows 7, Windows 8 and Windows 10

NOTE: This blog post specifically solves issues related to these error messages on installation of AutoCAD ADT 2012…

  • “This operating system is not supported by AutoCAD® Architecture®”
  • “You cannot install this product on the current operating system”
  • “You are attempting to use a 32-bit installer on a 64-bit operating system”
  • “This is a 32-bit AutoCAD® Architecture® 2012. It cannot be installed on 64-bit Windows”

NOTE: These steps do not bypass normal Autodesk licensing/authorization, you should expect to use your own serial numbers in the normal way.

Installing AutoCAD Architecture 2012 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. If you have CDs:
    1. Using Windows Explorer, make a backup of your Disk 1 of your ADT CD to your hard drive, to a folder path c:\Autodesk\adt2012
    2. Next, if you have a second CD, copy Disk 2 of your ADT CD’s directly over the top of Disk 1, overwrite all files in your previously copied c:\Autodesk\adt2012 folder
    3. Same again for Disk 3, if there is one
  3. If you have a single self extracting “??_sfx.exe” downloaded from Autodesk
    1. Run the exe, it will ask to unzip to a folder inside of c:\Autodesk, make a note of the folder for later use (we’ll refer to it from here as c:\Autodesk\adt2012), now click OK.
    2. Wait until all of the files have extracted, when they do, note that the ADT 2012 setup will automatically launch – make sure you close the setup and move to the next step.
  4. Now, start the Longbow Converter tool, select the 1st tab named “AutoCAD 32bit Installer Converter
    1. Next, using the ‘‘ button select the newly created c:\Autodesk\adt2012 folder, and click the ‘Convert‘ button.
      1. If the Converter complains that this is not a 32bit installer, make sure you select the folder which contains the setup.exe and the setup.ini files in the root of the installation media
  5. Once the conversion process is complete, simply click the “Install/Run Setup to start the setup.
    1. Now, just install as normal.
  6. Windows 8, Windows 8.1 and Windows 10 users…
    1. Once the installation process is complete, close the Setup program
    2. go back to the Converter…
      1. select the 3rd tab named “Old AutoCAD Program Reviver
      2. pick the newly installed C:\Program Files (x86)\\Autodesk\AutoCAD Architecture 2012 folder
      3. then click the ‘Fix‘ button.
  7. Now you can happily run your AutoCAD Architecture 2012 32bit on Windows 7, Windows 8, Windows 8.1 and Windows 10 64bit!
