Hello Sven,

Thank you for your message.

This error happens when you return/downgrade to an older version. Please try cleaning up your installation and then install Viewer from scratch. Here is a complete uninstall guide https://www.remoteutilities.com/support/docs/installing-and-uninstalling/#uninstall-viewer

Let us know if you need further assistance.

Thx Polina!

i was able to uninstall the Viewer and re-install from scratch. It works now.

Strange , all this happened during a normal upgrade of the Viewer....

Anyway. Happy Easter. BR Sven
