I have set a Keil MDK (FlexNet) license which I use, and on the receipt for the license there is a maintenance date and an entitlement date. The entitlement date is set to 2124, but does this mean I will not have to purchase a new license as long as I don't need maintenance? We only have one product that uses this license, so I don't think we'll need maintenance updates since what we have works as-is so far.
Please open a new Support Ticket if you have a question that is related to your license:

Thank you, Omer.
For anyone in the future who has the same question as me, the license acts as a perpetual license until the entitlement date. The maintenance date means any MDK products/updates released before the expiration can be used and Keil technical support is available until the expiration date, but not after.
