I need to recover my serial key for Acrobat XI Pro.

[adouglas_mte]

I have a copy of Adobe Acrobat XI Pro currently installed on a PC.  I do not believe it was ever registered, just installed with the serial key.  Unfortunately neither the box or install disc still exists.  Is there any way to retrieve a serial from my existing installation?  I still have the option to Deactivate this install.  I just want to move the install to a new PC.

adouglas_mte, good morning.
You cannot extract the serial key from an existing installation.
A serial key is like a key at home.
Just as you can't get into a house without a key at home, you can't install without a serial key.

Also Acrobat XI is a very old product. Due to a change in Adobe's policy, the installer cannot be obtained unless it is a downloaded version purchased from Adobe.com, so it can not be installed, and even if it can be installed, continuing to use an support ended product poses a security risk Because it is not recommended, I think it is better to consider switching to Acrobat DC of subscription type.

Lost information https://community.adobe.com/t5/Premiere-Pro/Find-serial-number-without-Adpbe-ID/td-p/7769446
- page has links to programs to find an installed serial number in Mac or Windows
- when you find your serial number(s) write them down and put in a desk drawer

If you never registered, probably not.  Log-in to your account below to check.

I think it's fair to say, you need a modern version of Acrobat.

For security reasons, old downloads are no longer available.

Free Acrobat Reader DC

Or if you need to do more, Acrobat Pro DC or Acrobat Standard
