When trying to activate the license file for the license server I get an error-message saying: “Feature XXX does not match the HOSTID of this computer”

The registration key is incorrect; please use UmLicenseServerRegistrationKey.exe to create the registration key. Note that UmLicenseServerRegistrationKey.exe must be run on the server where the license server will be installed.
The new registration key should be sent to Umetrics_delivery@sartorius-stedim.com. In this email please make sure the following information is available; your name, company/department, site, activation key/product key and registration key.
