Licence problem

We are using latest TV with corporate licence in a Windows Terminal Server.

Before we buy it, there was a free version installed (maybe V12).

Every time when I start TV there is a warning: licence not valid.

The licence is valid, and after click OK, everything fine.

I've uninstalled all, remove registry entries, reinstall, but the problem is the same.

Can you help me?

    Hello @fulopgy,

    Welcome in our Community! 🌻

    My assumption here, is that the ID of the impacted device(s) are still activated on your old TeamViewer 12 license you are mentioning.

    This could lead to such error messages.

    I recommend contacting our customer support and check if the IDs that are impacted have all been migrated to the new Coporate subscription.

    Let me know how this goes. 🍀

    All the best,
