What are kismain.exe Error Messages?


kismain.exe Runtime Errors

Runtime errors are Clean Master for PC errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when kismain.exe is attempted to be loaded either when Clean Master for PC is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using Clean Master for PC.

In most cases, kismain.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these kismain.exe error messages mean that Clean Master for PC was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Clean Master for PC will be unable to start without resolving these errors.

Some of the most common kismain.exe errors include:

  • kismain.exe - Bad Image.
