Run that setup file and it will install. There will be a license file In the protected folder that you use. It will be whatever key is NOT the corporate license manager (clm).
Once IDEA is installed, to use the application you will need to hold shift and right click on the shortcut. Once you do that the menu will pop up and select "Run as different user" and then when you get prompted type in the scwfuser account information.
If you need help with any of it, please put in a ticket.
