What are mrt_map.dll Error Messages?


Dynamic Link Library mrt_map.dll Errors

mrt_map.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mrt_map.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like wuauclt.exe - to follow. These files were created so that multiple programs (eg. Apple QuickTime Player) could share the same mrt_map.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 mrt_map.dll is attempted to be loaded either when Apple QuickTime Player is starting up, or in some cases already running. Some of the most common mrt_map.dll errors include:

Your mrt_map.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Apple QuickTime Player), or deleted by a malware infection. Furthermore, mrt_map.dll file corruption could be caused from a power outage when loading Apple QuickTime Player, system crash while loading mrt_map.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.



How to Fix mrt_map.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

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


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

  1. Hit the Windows Start button

  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 mrt_map.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve mrt_map.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 mrt_map.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying mrt_map.dll to your appropriate Windows system directory. Apple typically does not release Apple QuickTime Player 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 mrt_map.dll and all other DLL files for Apple QuickTime Player. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
