Hello src47,
Could you first check the version of Codemeter? The last version is 8.40. If you have an older one please install the lastest one from User Software - Wibu-Systems.
If this doesn’t solve the problem, deactivate firewalls and virusscanners and re-install PLCnext Engineer.
Please let us know if you still have problems after these steps.
Met vriendelijke groet / Mit freundlichen Grüßen / Best regards,
