Could you please help me reset the activation count or deactivate all previous devices associated wi

Hi, I’m using Adobe Acrobat Pro 2020 (perpetual license), and I’m getting the following error:

"The serial number [xxx] is already in use by the maximum allowed computers. You need to deactivate another computer within XX days to use this product."

Unfortunately, I no longer have access to the previous computers where the software was activated, so I cannot manually deactivate them.

Could you please help me reset the activation count or deactivate all previous devices associated with this serial number so I can activate it on my current computer?

Thank you very much!
