There’s nothing more frustrating than an error code that doesn’t convey much detail.
If you try to open Adobe Reader, seeing “Adobe failed to load core DLL” doesn’t tell you why the software can’t load, or how to fix it.
You can fix this problem, however, and regain Adobe Reader usage.
Some computer error messages provide you with unambiguous information about your system’s state and the problem that just arose to prevent you from performing a task.
Others leave you scratching your head, wondering if you have encountered a mild digital hiccup or a significant failure.
“Acrobat Failed to Load core DLL” may fall into either category, depending on which of the various causes prompted the message to appear.
Fixing Adobe Acrobat Failed to Load Its Core DLL
Interpret Error Message
For users of Microsoft Windows, the error message “Acrobat Failed to Load core DLL” endures through multiple versions of Adobe Acrobat and, more recently, with its free sibling product, Adobe Reader.
It appears when you attempt to launch the software, but the product cannot run. Adobe Systems tracked this error message to three potential causes, each requiring more corrective action than the previous one.
If you attempt these procedures in order from least to most drastic, you can stop your diagnostics as soon as your symptoms abate.
Adobe has traced the “Adobe failed to load core DLL” error to three causes. Adobe Reader might need to be repaired, malware may interfere, or the program may be corrupt.
However you want to use Adobe Reader again, it’s especially important to fix a malware problem if that is the cause.
The rootkit that interferes with Adobe Reader could steal your personal information. Attempt these repair solutions in the order they are presented.
Your Adobe product may have sustained damage, but not enough that would require removing the software and reinstalling it.
Adobe Reader includes self-repair capabilities you can access through the Programs and Features section of the Windows Control Panel.
When you select Adobe Reader and click on the “Change” option, you can access the repair feature and correct the problem.
If this procedure doesn’t produce the desired results, your computer may harbor a piece of malware that prevents Reader from operating as expected.
Rootkit infection conceals itself among your operating system’s basic functionality and alters the way Microsoft Windows operates.
This type of malware and the files through which it does its dirty work can remain invisible, although error messages such as this one in Adobe Reader can signal its presence indirectly.
Specialized malware cleanup (see Resources) can remove a redactor from your system. The free anti-malware program seeks out the rootkit, cures its infestation, and returns your system to normal after you reboot it.
If your system turns out to be free of malware but your copy of Adobe Reader still won’t run, you may be faced with fundamental software corruption.
When all else fails, remove and reinstall Adobe Reader to start fresh with a new copy of the software.
Instead of repairing the program through the Control Panel’s Programs and Features section, use the Remove option to wipe out your current version.
Visit the Adobe website (see Resources) and download the installer. The site checks your operating system and offers you a download based on the version it sees.
