The license manager is not going to be helpful for distributing standard PDF files. The license manager is for managing licenses for a piece of software that you have developed.
With WP eStore, you simply sell your PDF file (or allow customers to download a copy of it). If your PDF file is password protected, then the customers will need to enter a password to open the PDF file. You can send the password in the notification email (using product specific instructions feature of WP eStore plugin). All e-commerce software basically work that way. So I am not sure if that will help with what you are trying to do.
I don’t know of any ready-made solution out there that can do what you are suggesting (eg. limit the number of domains for a PDF file).
A PDF handling software like the following plugin maybe customized to do some of what you are asking but its still not going to be a perfect fit for what you explained:June 6, 2018 at 8:36 pm #32120sentinel42Member
OK thank you for suggestion to simply password protect a PDF. Not the best solution as that would mean the same PW for multiple purchasers and users of the same PDF but that’s OK. PDF Stamper seems to place a notice on each page which is overkill for my needs.
To clarify one of my questions… bypassing the license manager entirely, does using a serial key require the buyer of the PDF document to enter the serial key to open (use) it and if so is that serial key input required each time the document is reopened including, for example, by other people?

@sentinel42 — You cannot require “serial keys” for PDF files; only passwords. “Key” implies the document originator (you) can revoke it at any time.
The PDF format supports document “passwords.” And eStore supports using the purchaser’s email address as the document password.
Input of the password every time the document is opened, is dependent upon the settings of the user’s PDF reader. Even if the password is “remembered” by the reader software; copying the document to another device requires knowledge of the password.June 10, 2018 at 2:57 pm #32122sentinel42Member
So the user I send a password protected PDF to simply removes the password protection from the PDF (or changes it to something they want) before distributing it. Can that be done in Acrobat Reader of the person does not have Acrobat Pro or DC?? I did a test but because I have the pro DC version it wouldn’t let me edit the protection in the reader, kept pushing me to open the the pdf in DC

@sentinel42 — Are you using the PDF Stamper plugin, with eStore?
You can use the PDF Stamper to set the document password to match the email address of whoever purchases or downloads the file.
As for a person removing the stamps, watermarks, or passwords from a PDF file; more power to them. There are practical limits to the kinds of protection you can impose on user behavior, without getting into expensive (and sometimes ethical) solutions.
