Hello, check that your environment variables are set properly. This should be done automatically during installation of Amesim. You need an environment variable %AME% which points to the installation directory and PATH should also include %AME%\win64 (where that 'missing' dll should be) but also %AME%, %AME%\win32... If that is not the case, please reinstall Amesim with Administrator rights. If that still fails please get in touch with the person who gave you the training license.
