When running Quartus Prime SE, I get the following error while running the fitter: 119013 Current license file does not support the 5CSXFC6C6U23C7 device.

Check if the license for the Quartus Standard edition you have purchased does include support for the Cyclone V SX devices. If not, then you may have to purchase licenses for these devices or change the device to one thats supported by your installed licenses.

Also check if the license setup is pointing to the right license file, if its a node-locked or floating license.

Can you perform a Flexlm license diagnostics and post the output here so that the Intel reps can check out if you have the correct licenses..
