What are {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat Error Messages?


Dynamic Link Library {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat Errors

{C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. MediaFire) could share the same {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat 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 DAT 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 {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat is attempted to be loaded either when MediaFire is starting up, or in some cases already running. Some of the most common {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat errors include:

Your {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with MediaFire), or deleted by a malware infection. Furthermore, {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat file corruption could be caused from a power outage when loading MediaFire, system crash while loading {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat, 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.

Step 3: Perform a Windows Update.

  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat file version. We maintain a comprehensive database of 100% malware-free {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat files for every applicable version of MediaFire.

  1. Locate your Windows operating system version in the list of below "Download {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat Files".
  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate MediaFire folder location:
    Windows 10: C:\Users\Tester\AppData\Local\Packages\Microsoft.MicrosoftEdge_8wekyb3d8bbwe\AC\MicrosoftEdge\User\Default\Recovery\Active\
  4. Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.


GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat 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 {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat to your appropriate Windows system directory. MediaFire typically does not release MediaFire DAT 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 {C87EF641-37A6-4A17-A09D-FFC2F691EABF}.dat and all other DAT files for MediaFire. An incorrectly installed DAT file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
