Adobe Acrobat DC: an error has been detected with a required library or file

[lingz95456249]

Now every time I try to open the program I get the error message "An error has been detected with a required application library or file and the product cannot continue. Please reinstall the application."  It does not work even if I reinstall the program. So what happens? How to deal with it? (My system is Win 10)

I would use Adobe's "Cleaner" tool to remove any trace of your Acrobat installation, and then re-install from a fresh download. You can download the tool here: Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs

I tried all of this and other suggestions too but none worked for me. However, I found a fix. My issue was begin caused by malwarebytes. I had opened a pdf file containing malware. Immediately after, I started getting this message with Acrobat failing to open. I uninstalled and reinstalled Acrobat DC Pro multiple times with no success.When I stopped malwarebytes, I still could not open Adobe Acrobat. What I had to end up doing was completely removing both Adobe Acrobate DC Pro and malwarebytes. I then reinstalled Adobe Acrobat and it worked. After this I reinstalled malwarebytes and everything is back to normal.

The problem arises from the antivirus. I recently changed my antivirus and the next day I faced this problem. I changed the previously used antivirus and everything went back to normal.

Here's my solution....

Check your anti-virus program (SEP, McAffee, AVG, Microsoft) has not deleted or quarantined AMTLIB.DLL

It's an essential component of Acrobat and Adobe products, and I discovered that it had been deleted

I turned off my AV, reinstalled/repaired the Acrobat installation, and added an exception to my AV to ignore the file C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\amtlib.dll

Guess what, it worked.
