Licensing for Acrobat Reader DC on customer-facing RDP servers?

Hi,

I think that the license for Acrobat Reader DC volume distribution license does NOT allow what I want, but I just want to verify...

We have an RDP farm set up for our customers to access a custom application. On the desktop hosts that customers access, would we be allowed to install Adobe Acrobat Reader DC with the free volume distribution license? Seeing as this is perhaps not fully internal (the servers are, but the users are not), perhaps this is not covered by the license?

Thanks in advance.
