When you install you should not have to do anything with the license. Installation does it for you. The license installed by setup is the V103 license. Simply install and run the software. Regards, Rick B.
I did things oppositely... I downloaded both the license and the complete package thinking that if the package didn't provide a license (ie it failed) I would then try the license file. Never needed the license file since the ST3 install provides a new one and the computer was brand new (never had any version of SE 2D on it.)
