What are iis.chm Error Messages?


General iis.chm Runtime Errors

iis.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 iis.chm runtime errors:

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\WINDOWS\Help\iis.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 iis.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, iis.chm file corruption could be caused from a power outage when loading Windows, system crash while loading or saving iis.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 iis.chm 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 iis.chm 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.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  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 iis.chm error, please proceed to the Step 2 below.

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

System File Checker is a utility included with every Windows version that allows you scan and restore corrupted system files. Use the SFC tool to fix missing or corrupt iis.chm files (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "cmd" but DO NOT PRESS "ENTER".
  3. Press and hold "CTRL-Shift" on your keyboard while pressing "ENTER".
  4. You'll be prompted with a permission dialog box.
  5. In the box, click "YES".
  6. You should have a black screen with a blinking cursor.
  7. In that black screen, type "sfc /scannow" and hit "ENTER".
  8. SFC will begin scanning for iis.chm issues and any other system file problems.
  9. Follow any on-screen commands to complete the process.

Please be aware that this scan might take a while, so please be patient while it is working.

If this Step 2 fails as well, please proceed to the Step 3 below.

sfc /scannow

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 iis.chm 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 iis.chm error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve iis.chm problems.

If you are not currently backing up your data, you need to do so immediately.



Download iis.chm Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying iis.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 iis.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.
