Method 3: Temporarily disable your antivirus

Your error is sometimes caused by interference from antivirus software. To see if that’s the problem for you, temporarily disable your antivirus and check if the problem persists. (Consult your antivirus documentation for instructions on disabling it.)

If this resolves the problem, contact the vendor of your antivirus software and ask them for advice, or install a different antivirus solution.

IMPORTANT: Be extra careful about what sites you visit, what emails you open and what files you download when your antivirus is disabled.

Method 4: Update your Acrobat software

You may also get this error if you’re using an older version of Acrobat. You should try updating it to the latest version to see if this resolves the problem for you. You may need to uninstall the software, then download the latest version from the official Adobe website and install it on your computer.
