===== Solution =====

I found this after intensively searching the webs: https://www.plcnext-community.net/en/discussions.html?controller=attachment&task=download&tmpl=component&id=309:

> Open the “C:\Windows\System32\drivers\” or “C:\Windows\SysNative\drivers\” folder and check whether this folder includes a file called "Multikey.sys". You must delete this file.
> Before you delete this file, open Windows Device Manager (Control Panel) and check whether a driver called "Virtual USB Multikey X64" is installed.
> If this driver is installed, uninstall it before you delete the "Multikey.sys” file.
> If this driver is not installed, delete the "Multikey.sys” file straightaway.
>
> Note:
> Sometimes, the system uses the "Multikey.sys” file in the c:\windows\system32\drivers\ folder to emulate a dongle.
> **This file is blacklisted by Wibu, as it interferes with the Wibu license system.**
> Sometimes, you can even find the "Virtual USB Multikey x64" device driver when you open Windows Device Manager.
> If this driver exists, the "Multikey.sys” file will also exist.

After deleting this file and restarting windows Codemeter and Titan immediately work without problems.
