Acrobat and Reader only write back to the regsitry when you CLOSE the app. So, make the setting, close Acrobat - refresh your registry display. See what was written. Make the change in the Registry - re-launch to test. Most Acrobat/Reader registry entries are under HKCU. Meaning, the registry keys need to be imported for each user.
Like most programs you pay for, Adobe Acrobatrequires that you enter a unique serial number before using it. So, before you can install or reinstall Adobe Acrobat, you'll need to find the serial number that came with the program.
If you've lost your serial number, there's a very good chance you can retrieve it but only if Adobe Acrobat is still installed and the computer it's on is working.
You might be able to find your Adobe Acrobat serial number if you've uninstalled the program but only if the serial number information was left in the Windows Registry. We'll go over everything you need to know below.
The Adobe Acrobat serial number is actually more of a product key than a serial number but the terms are often used interchangeably. Pdf reader software free download for windows 10.
How to Find Your Adobe Acrobat Serial Number
The easiest way to find your Adobe Acrobat DC or Acrobat X serial number is with a product key finder program.
Product key finder programs automatically search your computer for the product keys and serial numbers that your software programs store in the registry, Adobe Acrobat included.
See our Free Product Key Finders list for a number of programs that do just this. Not only that, they'll find your Acrobat serial for free. Most of the programs in that list are small and really easy to use.
The programs we've linked to will find the serial number for any recent edition of Acrobat, including Adobe Acrobat DC (Pro or Standard), Adobe Acrobat X, Adobe Acrobat 9, etc.
For example, Belarc Advisor, one of our favorite key finder tools (and the program shown in the example below), will properly locate the serial number for any version of Adobe Acrobat you have. If you find that another does for sure, let me know so I can keep this page updated.
The serial numbers in this picture have been greyed out but you'll see yours listed on the right side in plain text.
Most product key finder programs are designed to find serial numbers and product keys for operating systems, like Windows 10 or Windows 8, but some of them find serial numbers for several other programs as well — programs like Adobe Acrobat.
Other Ways to Find a Lost Adobe Acrobat Serial
While a keyfinder tool is certainly the easiest way to do this, no, it's not the only way.
If you're a little more technically inclined, there are a few additional ways to get your hands on a lost Acrobat serial number:
Ask Adobe for Your Acrobat Serial Number
It'd be unwise of me to skip the obvious — maybe Adobe can help! Depending on how, when, and from whom you purchased Adobe Acrobat, you may be able to contact Adobe and get your Acrobat serial number from them.

Dig Up Your Acrobat Serial Number & Manually Decrypt It
Fortunately, the exact registry key that stores your Adobe Acrobat serial number is well known, as is a database file that stores it.
If you're comfortable in the Windows Registry, your Adobe Acrobat serial is located in HKEY_LOCAL_MACHINE. Below is the exact location, depending on the version of the program and whether or not you're running a 64-bit or 32-bit version of Windows.
64-bit:
32-bit:
If you see multiple folders under Adobe Acrobat, replace 11.0 in the path above to whatever version of Acrobat you have.
Your other option is to grab the cache.db file from C:Program Files (x86)Common FilesAdobeAdobe PCDcache and open it with any free SQLite database viewing tool.
Please know that this serial number is encrypted, meaning that what you find in the registry key or the database file is not the literal serial number you can enter to install Adobe Acrobat. You'll first have to decrypt the serial number.

Acrobat Serial Number Generators & Cracks
Don't do that. There's no other way to put it.
While you may have come across Adobe Acrobat key generator programs or other kinds of Adobe Acrobat cracks, please know that these are not legal ways of obtaining a working serial number.
The only legal way of installing this program is by using a valid Adobe Acrobat serial number obtained through a legal purchase of the software.
If all else fails, you may be left with the final option of buying a new copy of the software. Amazon has great prices on most versions of Adobe Acrobat, plus options for previously used boxed copies as well.
Another option is to abandon Adobe Acrobat altogether and choose a free tool that does the same thing. Seriously. While not as robust, there are a number of other options out there.

Privileged (Protected Mode)
Sandboxing is a technique for creating a sandbox (confined execution environment) for running untrusted programs. In the context of Adobe Reader, the 'untrusted program' is any PDF and the processes it invokes. When Reader sandboxing is enabled, Reader assumes all PDFs are potentially malicious and confines any processing they invoke to the sandbox.
