By default, Quantum on windows displays a warning when you run it within thirty days of your license expiring. Normally you will have received an update before you get the warning, but if you have not, contact UNICOM Systems, Inc.

When you see the message, press RETURN to continue the run as normal.

Quantum gives the warning every time you run it within 30 days of the license expiring. If you would prefer not to see the message, you can suppress it by setting the environment variable QTNOWARN.
