Q100526: "Invalid SystemID" and "Wrong host for license" error messages


A license will only work if the SystemID it is generated for is a valid SystemID for the machine it is installed on. 



Attempting to use a license with an invalid SystemID will produce an error message in the application or prevent a license server from running.

The Foundry Licensing Utility (FLU) will only install licenses for SystemIDs that are valid for the machine it is running on.


Error message within an application

If an application can only find a license with an invalid SystemID it will fail to launch and show an error message saying "wrong host for license" in the Status window of the applications licensing dialog.



Error message from the Foundry Licensing Utility (FLU) 

If you try to install a license with an invalid SystemID the FLU with report that the license is invalid due to having a different SystemID. 


NOTE: If you pass the FLU multiple licenses to install it will install any valid licenses (such as those with valid SystemIDs) and produce a warning message for any invalid licenses.

Error message from RLM Server log

If you try and float a server license for an invalid SystemID the server log will include a message that the license is "not on this host".
