Acrobat DC - per device licencing

[clareq]

I'm trying to create a package for Adobe Acrobat. We have a per device licence model, and I have successfully created packages for all the other CC applications we're licenced for. From what I can work out from the Adobe help files, I use the CC Customiser for Acrobat in the same way I did for all the other apps. and then use the Acrobat customiser to apply any changes. However, trying to install it always asks for a serial number - there isn't one. Is there a strange secret society I need to belong to to obtain such a serial number for a per device install? I've been round n circles on the Adobe site. I hope to use SCCM to deploy the program.

 

Help!!
