Installing 32bit AutoCAD Mechanical 2008 on Windows 7, Windows 8 and Windows 10

NOTE: This blog post specifically solves issues related to these error messages on installation of AutoCAD Mechanical 2008…

  • “This operating system is not supported by AutoCAD® Mechanical®”
  • “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® Mechanical® 2008. It cannot be installed on 64-bit Windows”

Installing 32bit AutoCAD Mechanical 2008 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.

  1. Obtain your copy of the Longbow Converter here
  2. If you have CDs (if not check (3) below):
    1. Using Windows Explorer, copy Disk 1 of your AutoCAD Mechanical 2008 CD to your hard drive, to a folder path c:\Autodesk\AutoCADM2008
    2. If you have more CD’s, copy them all directly over the top of Disk 1, overwrite all files in your previously copied c:\Autodesk\AutoCADM2008 folder
  3. If you have a single self extracting 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\AutoCADM2008), now click OK. Wait until all of the files have extracted, when they do, the AutoCAD Mechanical 2008 setup will automatically launch – simply close it and move to the next step.
  4. Now, start the Longbow Converter tool, select the 1st tab, pick the c:\Autodesk\AutoCADM2008 folder, and click the Convert button.
  5. Once the conversion process is complete, click Install/Run Setup to start setup. Simply install as normal.
  6. Windows 8, Windows 8.1 and Windows 10 users: Once the installation process is complete, go back to the Converter, select the 3rd tab, pick the newly installed C:\Program Files (x86)\AutoCAD Mechanical 2008 folder, then click Fix
  7. Now you can happily run your AutoCAD Mechanical 2008 32bit on Windows 7, Windows 8, Windows 8.1 and Windows 10!

  4. In the AutoCAD R14 setup program…
    1. navigate through each setup dialog as normal, with these exceptions…
      1. Make sure you do a Typical Install (not a Full Install)
      2. When you get to the installation folder input dialog **it’s vitally important to make sure you install to c:\acadR14 (not .\AutoCAD R14 as usually prompted)**
  5. Now carry on with the install
    1. Do not reboot once the install is complete
    2. Ignore any errors related to not being able to create the shortcut e.g. “Cannot Create folder ‘AutoCAD R14’“, you will have to create a shortcut on your computer Desktop to your c:\acadR14\acad.exe by hand.
