Enter the serial number? Strange that a new laptop should come with a version of Acrobat discontinued over 5 years ago, were you expecting that?
You might check with the vendor you purchased the laptop from. Some pre-installed software these days comes as a trial, some comes installed but without the ability to reinstall. It sucks, I know, but it depends on the company who sold it to you and / or the company who made the computer. We can't tell what they did on your computer.
Google "pre-installed software" for more info.
As Test Screen Name said, Acrobat X has been discontinued. The version after that—Acrobat XI—is no longer supported either.
The current versions are Acrobat 2017 and Acrobat DC. If you don't get anywhere with the manufacturer or the place where you bought it, and you still want Acrobat, check into the newer versions--they are awesome! But you can try taking it up with them first if want to pursue the old version that you no longer have.
Good luck, and report back.
@Test Screen Name, Yes it comes with Adobe Acrobat X Pro as the full version surprisingly, and no i wasn't expecting that.
@jane-e, the laptop I am using are for work purposes. Apparently X Pro doesn't work well with Windows 10 and crashes frequently in my office. I considered getting DC but to pay annually for it is crazy. Thanks for the help.
I think you'll need to contact the sender, if you paid for this. If you didn't pay for it specifically, perhaps it was a trial version that's now finished, but you couldn't pay for it anyway. Acrobat DC comes as subscription and permanent license versions.
Acrobat 2017 was released in June 2017 and is not subscription. It will get updates, but not any new features that the subscription Acrobat DC will get. It comes in Pro and Standard.
Test Screen Name I spent a half an hour talking to the Acrobat team when I was at Adobe MAX. Acrobat DC no longer has a permanent license version (unless, of course, you want to call that Acrobat 2017!)
