What are extension.msc Error Messages?


extension.msc Runtime Errors

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

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

Some of the most common extension.msc errors include:

  • extension.msc - Bad Image.
  • extension.msc Application Error.
  • extension.msc could not be found.
  • extension.msc could not be installed.
  • extension.msc could not be launched. Class not registered.
  • extension.msc could not be started.
  • extension.msc failed to initialize properly.
  • extension.msc has encountered a problem and needs to close. We are sorry for the inconvenience.
  • extension.msc is not a valid Win32 application.
  • extension.msc is not running.
  • Cannot find extension.msc.
  • Error starting program: extension.msc.
  • Faulting Application Path: extension.msc.
  • The file extension.msc is missing or corrupt.
  • Windows failed to start - extension.msc.
System Error


The program can’t start because extension.msc 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 extension.msc error is key to properly resolving these errors. Although most of these MSC errors affecting extension.msc will happen during startup, occasionally you will encounter a runtime error while using Crimson Editor 3.72. This can occur due to poor programming on behalf of Ingyu Kang, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of extension.msc 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 extension.msc issue. These troubleshooting steps are listed in the recommended order of execution.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many extension.msc error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  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 extension.msc error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your extension.msc File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate extension.msc file version. We maintain a comprehensive database of 100% malware-free extension.msc files for every applicable version of Crimson Editor. Please follow the steps below to download and properly replace you file:

  1. Locate your Windows operating system version in the list of below "Download extension.msc Files".
  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate Crimson Editor folder location:
    Windows 10: C:\Program Files (x86)\Emerald Editor Community\Crimson Editor SVN286M\link\
  4. Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.


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


CAUTION : We strongly advise against downloading and copying extension.msc to your appropriate Windows system directory. Ingyu Kang typically does not release Crimson Editor MSC 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 extension.msc and all other MSC files for Crimson Editor. An incorrectly installed MSC file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
