Installing 32bit AutoCAD 2011 on Windows 7, Windows 8 and Windows 10

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

  • “This operating system is not supported by AutoCAD® 2011”
  • “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 2011®. It cannot be installed on 64-bit Windows”

Installing AutoCAD 2011 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.

  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 2011 CD to your hard drive, to a folder path c:\Autodesk\AutoCAD2011
    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\AutoCAD2011 folder
  3. If you have a single self extracting exe downloaded from Autodesk (something like AutoCAD_2011_Multilingual_Americas_WIN_32bit.exe)
    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\AutoCAD2011), now click OK. Wait until all of the files have extracted, when they do, the AutoCAD 2011 setup will automatically launch – simply close it and move to the next step.
  4. Now, start the Longbow Converter tool
    1. select the 1st tab named “AutoCAD 32bit Installer Converter
    2. Using the ‘‘ button, pick the c:\Autodesk\AutoCAD2011 folder
    3. 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 2011 folder, then click Fix.
  7. Now you can happily run your 32bit AutoCAD 2011 on Windows 7, Windows 8 and Windows 10!

  1. Your blog talks about 32 bit autocad, is there any other? I cannot find any information saying what bit autocad I have. I know my computer is 64 bit. I have autocad 2011 upgraded trough audesk to 2012 and want to make it work on a windows version 10. Will your software provide a permanent fix or would I encounter problems every time there is a window update. Also the fees given are they in American dollars?
