Reinstalling Acrobat Pro 2020 lifetime license for Mac?

[John322939496xnn]

I bought the program one year ago as a lifetime license (not subscription). Now I need to restart my Mac from scratch, which means I need to install all my purchased software again. My Acrobat Pro 2020 shows up as "Installed" in Creative Cloud, but I cannot find a license key or similar? What should I do to be sure I can reinstall after resetting the computer? I cannot remember where I bought it and I can't find any confirmation email from that time... I believe it may have been from g2a.com.

Did you register it with Adobe? If so, the serial number will be available under your account on their website.

If not, you must find the serial-number (it's not available in the application itself), or you won't be able to use it later on.
