Hi Oskars, yes PDM Standard has its own serial number. You will need to contact your SolidWorks reseller to obtain the serial number.
Thanks, already did it! Turns out they gave me only one serial for server and forgot to give client licenses.
As PDM Standard licensing uses Network licensing, you need to have the SNL License Manager installed on the server and enter the PDM Standard serial in the installation.
(If SNL License Manager is already in use then change the installation and add the PDM Standard serial to it, separated by comma).
After that activate/reactivate the SNL license.
Then add the license server port (25734@licenseservername) in the PDM administration at "license") to tell PDM to use that license server.
