What are ngcpopkeysrv.dll Error Messages?


Dynamic Link Library ngcpopkeysrv.dll Errors

ngcpopkeysrv.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like ngcpopkeysrv.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like HelpPane.exe - to follow. These files were created so that multiple programs (eg. Microsoft Office Access 2010) could share the same ngcpopkeysrv.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when ngcpopkeysrv.dll is attempted to be loaded either when Microsoft Office Access 2010 is starting up, or in some cases already running. Some of the most common ngcpopkeysrv.dll errors include:

Your ngcpopkeysrv.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Office Access 2010), or deleted by a malware infection. Furthermore, ngcpopkeysrv.dll file corruption could be caused from a power outage when loading Microsoft Office Access 2010, system crash while loading ngcpopkeysrv.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your ngcpopkeysrv.dll issue. These troubleshooting steps are listed in the recommended order of execution.

  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the ngcpopkeysrv.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

  4. Restart your computer.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve ngcpopkeysrv.dll problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.



Download ngcpopkeysrv.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying ngcpopkeysrv.dll to your appropriate Windows system directory. Microsoft typically does not release Microsoft Office Access 2010 DLL files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing ngcpopkeysrv.dll and all other DLL files for Microsoft Office Access 2010. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
