help cannnot transfer Acrobat 2020 serials to new devices

@marcus_2238 that is correct in contacting and DMing Adobe. Because this is an Adobe 'User' Forum, sometimes Adobe employees will come in here and help when they can. The problem of "stuck" serial numbers for your Acrobat 2020 perpetual licenses arises because deactivation must be explicitly performed on the original computer and is not automatic upon uninstallation or device formatting. When a perpetual license is activated, Adobe's servers record that activation against a specific hardware ID, even if it's not tied to a registered user account. If the original machine is lost, formatted, or inaccessible, the license remains technically active on the dead hardware, which causes the "Maximum Activations Reached" error when you try to install it on a new computer. I would say, since you bought 47 licences, you might have bought this through an Adobe sales rep? If so, maybe find that email for contact information—this is critical because Acrobat 2020 perpetual licenses official End of Support (EOS): November 30, 2025! Since the End of Support date is November 30, 2025, and your issue is about serial numbers and activation (which falls under technical support and license management), you are still entitled to direct support from Adobe.

The clock is ticking on official support, so you should contact them soon with your list of serials. Create a spreadsheet of all the "stuck" serial numbers (or the original set of 47 licenses, if easier) and indicate which ones are causing the "Maximum Activations" error. Good luck!
