Unfortunately this is what is made available on this site under Mitsubishi demo software. We are using this version in our class for training because it is free. I spoke to the other two people in class that are using Windows 7 64-bit Home Premium. They were able to get it to install and it is running fine. I am trying to instal in safe mode. Still having difficulty, but able to execute setup. I will look on Microsoft's forums for help. I get an error with the EnvMEL setup.exe. There is a -119 error pertaining to the MFC40.dll file. if there is a newer free version that our class can have access to, I would be glad to forward it on to my instructor.
