You can't do without the serial number while you install, reinstall, or activate Adobe Acrobat (9/X/XI Pro) or other versions of Acrobat. If you are planning on reinstalling or transferring Adobe Acrobat to a new computer but can't find the serial number, this could be quite troublesome. But take it easy. As long as Adobe Acrobat has been installed on your computer, the serial number has been stored in your Windows Registry. You have some options to find serial number for Adobe Acrobat on your computer.

• Option 1: Using product key finder software
• Option 2: In Windows Registry
• Option 3: Ask your product provider

Option 1: Find serial number for Adobe Acrobat with product key finder

It should be the easiest and quickest way to use a specialised product key finder program.

Step 1: Download, install, and then launch the iSumsoft Product Key Finder program on your computer on which Adobe Acrobat has been installed.

Step 2: Click on the Start Recovery button near the lower left corner.

Step 3: It will quickly find all the product keys or serial numbers for all software product including Adobe Acrobat on your computer and shows them in the list.

Step 4: Click on the Save button or the Save to File button to save the serial numbers into a Notepad. Then you can open the Notepad to view the serial number when Adobe Acrobat asks for a serial number.

Option 2: Find Adobe Acrobat serial number in Windows Registry

At the beginning of this article, I mentioned that serial number has been stored in system Registry as long as the genuine Adobe Acrobat has been installed. So you can manually open Windows Registry to find the serial number.

Step 1: Press Win + R to open Run dialog, type regedit, and click OK.

Step 2: Confirm the User Account Control if prompted.

Step 3: The Registry Editor opens. Navigate to HKEY_LOCAL_MACHINE -> SOFTWARE -> Adobe -> Adobe Acrobat -> 9.0 -> Registration. There in the right pane you can find the serial number.

Tips: If your Windows version is 64-bit, navigate to HKEY_LOCAL_MACHINE -> SOFTWARE -> Wow6432Node -> Adobe -> Adobe Acrobat -> 9.0 -> Registration.

Step 4: But the serial number you can see is a series of encrypted number instead of the real serial number you can use to install Adobe Acrobat. You have to use a product key generator to decrypt the serial number.

Option 3: Ask your Adobe Acrobat provider for the serial number

You can ask the provider from whom you got or bought Adobe Acrobat for the serial number. If you bought it on the Internet, you may be able to find the serial number in your email box.
