What are mrt.exe Error Messages?


mrt.exe Runtime Errors

Runtime errors are Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit) errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when mrt.exe is attempted to be loaded either when Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit) is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit).

In most cases, mrt.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these mrt.exe error messages mean that Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit) was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Realtek High Definition Audio Codec (Windows 7 / 8/ 8.1/ 10 64-bit) will be unable to start without resolving these errors.

Some of the most common mrt.exe errors include:

  • mrt.exe - Bad Image.

  • mrt.exe could not be found.
