What are perfmon.CHM Error Messages?


General perfmon.CHM Runtime Errors

perfmon.CHM file errors often occur during the startup phase of Windows, but can also occur while the program is running. These types CHM errors are also known as “runtime errors” because they occur while Windows is running. Here are some of the most common perfmon.CHM runtime errors:

Runtime Error!

Program: C:\Windows\Help\mui\0409\perfmon.CHM

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.


Most CHM errors are due to missing or corrupt files. Your perfmon.CHM file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Windows), or deleted by a malware infection. Furthermore, perfmon.CHM file corruption could be caused from a power outage when loading Windows, system crash while loading or saving perfmon.CHM, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix perfmon.CHM Errors in 3 Steps (Time to complete: ~5-15 minutes)

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the perfmon.CHM error, please proceed to the Step 2 below.

Step 2: Run SFC (System File Checker) to restore the corrupt or missing perfmon.CHM file.

  3. Press and hold "CTRL-Shift" on your keyboard while pressing "ENTER".
  4. You'll be prompted with a permission dialog box.

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