When using Royal Server you see the following message:

Licenses are reused on different Royal Servers. Please ensure you install licenses only once.

This might be shown for a Personal License (non-commercial) where only one installation is allowed.


You might see this message although you only have one installation in your environment but you you access this server with different names or IPs. 

If thats the case, please make sure you only access your Royal Server with one IP or name and restart Royal TS/X to make the change working.
