@pavulon5 Might be a permissions issue. Repair your SketchUp install by downloading the SketchUp installer. Right-click the .exe and choose Run as Admin and choose Repair when prompted If your device is named using non-alphanumeric characters, áéíóú etc, please change it to only use alphanumeric. Other option is to go to C:\Users\SomeName\AppData\Local\SCF Licenses and delete your signature file. Restart SketchUp to generate a new one and try license. The error is related to the signature file.
