Activate Solidworks with LicenseManager

Hey guys,

I've an Licenseserver and want to install Solidworks with using theLicense on the server.
I already added the server in the licensemanager but everywhen Iwant to install SolidWorks i need to type in an serialnumber.
But I don't have any serialnumbers - only 6 licenses on the server.

How can I install & activate Solidworks without typing in anserialnumber and using the license on the server?

Best regards
