Ransomware Protection Windows 11 and AutoCAD

Just before we start note that Windows 11 comes with a Ransomware Protection which includes Controlled Folder Access. Controlled folder access blocks applications from writing to your Documents, Pictures, Videos, Music, Public and Favorites folders. AutoCAD versions all the way to AutoCAD 2021 write to certain user Public folders and are therefore blocked by this feature. This can cause issues with all sorts of things including activating your AutoCAD license and even running AutoCAD. Ransomware Protection is an important feature of Windows 11 but it will affect your AutoCAD unless you allow AutoCAD and its dependent applications access to the controlled folders.

Installing 32bit AutoCAD Electrical 2010 on Windows 7, Windows 8, Windows 8.1 or Windows 10 64bit can be very easily defined in these short steps.

  1. First of all, you need V9.20 of the Longbow Converter (or newer) – obtain the latest version of the Longbow Converter here
  2. If you have CDs (if not skip to step 3 below) you must copy ALL CDs to your hard drive using the following instructions…
    1. Using Windows Explorer, copy Disk 1 of your AutoCAD Electrical 2010 CD to your hard drive, to a folder path c:\Autodesk\AutoCADE2010
    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\AutoCADE2010 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 name created for later use (we’ll refer to it from here as c:\Autodesk\AutoCADE2010), now click OK.
    2. Wait until all of the files have extracted, when they do, the AutoCAD Electrical 2010 setup will automatically launch – simply close it and move to the next step.
  4. Next start the Longbow Converter tool (V9.20 or newer)
    1. select the 1st tab named “AutoCAD 32bit Installer Converter
    2. Pick the c:\Autodesk\AutoCADE2010 folder (where you copied the CDs to)
    3. then click the “Convert… button
  5. Once the conversion process is complete
    1. click Install/Run Setup to start setup.
    2. Install as normal, EXCEPT – you must install to “c:\AcadE2010” (<<< the exact text, anything else will fail!) instead of c:\Program Files (x86)\AutoCAD Electrical.
    3. NOTE: Be sure to download any updates that the setup offers you.
  6. Windows 8 users: Once the installation process is complete, go back to the Converter, select the 3rd tab, pick the newly installed C:\Program Files (x86)\Autodesk\Acade 2010 folder, then click Fix Old Program
  7. Now you can happily run your AutoCAD 2010 32bit on Windows 7, Windows 8, Windows 8.1 and Windows 10.

Troubleshooting:

  1. If your installed AutoCAD is hanging on startup then read this post first AutoCAD Freezes on startup (AutoCAD visible but the menus don’t appear)
  2. if your AutoCAD hangs on startup (stuck at the “Checking License…” message, try installing the 32bit version of AutoCAD 2010 on 64bit Windows – we’ve actually found the 32bit AutoCAD 2010 running on 64bit Windows is much more stable and actually faster than the 64bit version of AutoCAD 2010.
  3. If your AutoCAD crashes while interacting with the Ribbon click here
  4. If you are unable to activate your product, or the activation process crashes:
    1. Try uninstalling the July 2014 Microsoft security update
    2. Try downgrading your Internet Explorer (IE) from version 11 to version 10 by following the instructions detailed here
  5. If you have crashing problems using the File->Open or File->Save dialogs inside of AutoCAD please read this blog entry on the File->Open or File->Save Crash in AutoCAD
