SolidWorks error: “Could not load SolidWorks DLL: GdtAnalysisSupport.dll.”


  1. Go to windows ‘Start’ > type cmd
  2. RMB on ‘cmd.exe’ > select ‘Run as administrator’
  3. In windows explorer Navigate to , (where sldworks.exe is contained)
  4. Drag and drop ‘sldworks.exe’ in command prompt and type /regserver
    • Typically the command would look like “C:\Program Files\SOLIDWORKS Corp \SOLIDWORKS\sldworks.exe” /regserver
  5. Press ‘Enter’ > this will register ‘sldworks.exe’
  6. Reconfirm behavior.
