Acrobat Pro 2017 - commercial license number of pcs

Hi there has anyone had experience loading a commercial license onto multiple pcs? I can't find clear information as to how many tablets (windows based) or notebooks I can load this onto. Exact product I'm looking at is Adobe Acrobat Pro 2017 commercial license rrp $739 AUD, I have 3 surface tablets and 2 hp notebooks that require this software
