Acrobat/Reader: “Acrobat fail to load it’s Core DLL” error after installation


 If you have installed Reader/Acrobat and are having problems starting it, you may receive the following error message:

"Acrobat fail to load it's Core DLL"


Acrobat/Reader 6 or 7:

This error occurs if you are installing Acrobat/Reader to a Windows NT platform.  There is a BIOS setting “limit CPUID Function” that should be enabled for NT machines and disabled for Windows XP/2000 machines.

Later Acrobat/Reader versions

This error has also been reported with later Acrobat/Reader versions when computers were infected with malware.  The virus/malware can usually be detected and removed with the use of Kaspersky TDSSKiller tool.  We would strongly recommend that you clean any infected systems immediately as this malware could be used to steal personal data from your computer.


Acrobat/Reader 6 or 7:

With this setting enabled on Windows NT in the BIOS the problem does not occur.

Later Acrobat/Reader versions:

If you are facing this issue, we recommend running the Kaspersky TDSSKiller tool on your system. For installation and usage instructions, please refer to “How to disinfect a compromised system” on

Additional Information

If the solutions above do not help it may be because the Acrobat/Reader installation is corrupted.  You should try to repair the installation, or do a complete uninstall, download and re-install.  Also check your permissions on the Adobe installation folder and ensure you have adequate permissions.  It has also been reported that some anti-virus programs cause conflicts in Acrobat/Reader.  There are further details in the following technote:

Acrobat/Reader7: how to disable the “Keep forms data temporarily on disk” option


 If you are using Reader 7 you may want to disable the option “Keep forms data temporarily on disk“.


 This prevents form data being cached on the local disk, which may pose data integrity/security risks to enterprise customers.


There are a few workarounds to disble this functionality:

1. create a registry key to disable the option automatically:

The location is [HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\7.0\Originals].

Create the key named bCacheFormData.

Create a dword value of 00000000.

Close registry and relaunch Acrobat/Reader.

2. Another option is to control this in the form itself using JavaScript

From the Acrobat JavaScript Scripting reference available at

this.nocache = true; 

This will only have an affect in the form context.

3. Your third option is to use the Web browser settings:

Set the preference “Do not save encrypted pages to disk” as checked.

Empty Temporary Internet Files Folder when browser is closed.

Additional Information

 This setting has been disbled by default in Acrobat/Reader 8.0 and later versions.
