Premiere Elements 13 serialize Return Code = 14

I have 24 AOO licences of Premiere Elements 13 that I need to deploy with SCCM.

I have created an .msi with AAMEE as I was told by Adobe support. Next I tried to create a prov.xml with the following command:

adobe_prtk.exe --tool=VolumeSerialize --generate --serial=xxxx-xxxx-xxxx-xxxx-xxxx-xxxx --leid=V7{}PremiereElements-EMT13-Win-GM --regsuppress=ss --eulasuppress --provfilepath="path to desired folder"

I get Return Code = 14. I am running the command prompt as administrator. What have I done wrong?
