Not a valid win32 application
After installing Simul8, you might come across this message:
“C:\S8SETUP.EXE is not a valid win32 application”
This message is seen when your download hasn't completed successfully. Even if there are just a few bits missing, your installer will not be able to execute properly.
To resolve this, delete the installation file you have downloaded, re-download it, and run the installation again. Deleting the file is important because often your computer tries to be clever and remembers you've already downloaded the file, so it doesn't really download it.
