ModelSim: can’t read “_clients()”: no such variable


I am using ModelSim Altera 10.3d Quartus II 15.0 starter edition. When I open it I get an error message

For Windows:

  1. Click on the Start button on the desktop and search for ‘regedit’
  2. Expand ‘HKEY_CURRENT_USER’ > Expand ‘Software’ > Expand ‘Model Technology’ > Choose ‘ModelSim
  3. Delete all the files from this folder
  4. Restart ModelSim

For Linux:

There should be a “.modelsim” file in your home directory. Please delete this file and then when you restart ModelSim it will automatically create a new .modelsim file for you.
