What are UninstallerHelper.exe Error Messages?

UninstallerHelper.exe Runtime Errors

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

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

Some of the most common UninstallerHelper.exe errors include:

UninstallerHelper.exe - Bad Image.
UninstallerHelper.exe Application Error.
UninstallerHelper.exe could not be found.
UninstallerHelper.exe could not be installed.
UninstallerHelper.exe could not be launched. Class not registered.

System Error

The program can’t start because UninstallerHelper.exe is missing from your computer. Try reinstalling the program to fix this problem.

Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Finding the source of the UninstallerHelper.exe error is key to properly resolving these errors. Although most of these EXE errors affecting UninstallerHelper.exe will happen during startup, occasionally you will encounter a runtime error while using Uninstaller. This can occur due to poor programming on behalf of IObit, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of UninstallerHelper.exe errors can occur if it has been accidentally moved, deleted, or corrupted by 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 UninstallerHelper.exe issue. These troubleshooting steps are listed in the recommended order of execution.

Restore your computer to that backup image.

If the Step 1 fails to resolve the UninstallerHelper.exe error, please proceed to the Step 2 below.
