  3. Navigate to the product folder. For example: C:\Program Files\Autodesk\AutoCAD 2018

    (Substitute the applicable product name.)

  4. In this folder, rename the acdb22.dll file to acdb_old.dll.
  5. Unzip the attachment in this article and copy the correct file to the location where you just renamed the acdb22.dll file:
