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

Issue

 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"

Reasons

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.

Solutions

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 http://support.kaspersky.com/5350?el=88446

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: http://helpx.adobe.com/acrobat/kb/reader-core-dll-error.html

  3. Fantastic! For those who are useless at checking for drivers by themselves, just like me, I found and installed everything I needed in no time at all with your kind share. My PC is now running perfectly without errors. Bookmarked it. Thank you!
