Invalid -inconsistent- License Key --8 544 0- Solidworks 2020 Guide

At 8:44 PM—she glanced at the clock—Marta made a decision. She unplugged the Ethernet cable, rebooted, and ran the software offline. For ten minutes, it worked. Then the error returned. The license had phoned home somehow, or the local validation had decayed.
