  Good morning,
  I am trying to use a matlab script to automate MotorCAD simulations but now it does not worked even if it used to. When I use the command
  mcad = actxserver('motorcad.AppAutomation');
  I receive the error
  Error using feval
  Server Creation Failed:
  Error in actxserver (line 89)
  h=feval(['COM.' convertedProgID], 'server', machinename, interface);
  Error in Main (line 2)
  mcad = actxserver('motorcad.AppAutomation');
  Did anyone have a similar issue?

  Hi, this could relate to installation.
  
  Here is a similiar actxserver issue in Matlab with Excel, and MathWork support team shared 8 solutions for fixing the issue, including using environment variable to help re-registering the application: search "actxserver "Server creation failed: server execution failed" error when trying to create COM object with EXCEL - MATLAB Answers - MATLAB Central" for more details.
