What are chrmstp.exe Error Messages?

chrmstp.exe Runtime Errors

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

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

Some of the most common chrmstp.exe errors include:

  • chrmstp.exe - Bad Image.
  • chrmstp.exe Application Error.
  • chrmstp.exe could not be found.
  • chrmstp.exe could not be installed.
  • chrmstp.exe could not be launched. Class not registered.
  • chrmstp.exe could not be started.

System Error

The program can’t start because chrmstp.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 chrmstp.exe error is key to properly resolving these errors. Although most of these EXE errors affecting chrmstp.exe will happen during startup, occasionally you will encounter a runtime error while using Google Chrome Installer. This can occur due to poor programming on behalf of Google LLC, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of chrmstp.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.

How to Fix chrmstp.exe 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 chrmstp.exe 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

Step 2: If recently installed Google Chrome (or related software), uninstall then try reinstalling Google Chrome software.

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

CAUTION : We strongly advise against downloading and copying chrmstp.exe to your appropriate Windows system directory. Google typically does not release Google Chrome EXE 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 chrmstp.exe and all other EXE files for Google Chrome. An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
