Test for Valid License - by: jgyenese

Is there any way to test that the license is valid using code? Or perhaps a way to instruct it not to run as a demo if the license is invalid? I don't want to have to wait 30 minutes for something that the software already knows.

I am fanatical about keeping my software up to the latest version, but sometimes the new version is newer than the license file in my installer project. I just had an issue where I sent a customer a version that timed out and they weren't very happy.

Thank you.
