What are ap_compat.h Error Messages?

General ap_compat.h Runtime Errors

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

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\wamp\bin\apache\apache2.4.41\include\ap_compat.h

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

Most H errors are due to missing or corrupt files. Your ap_compat.h file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with WampServer), or deleted by a malware infection. Furthermore, ap_compat.h file corruption could be caused from a power outage when loading WampServer, system crash while loading or saving ap_compat.h, 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.

Step 3: Perform a Windows Update.

If Windows Update failed to resolve the ap_compat.h 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 ap_compat.h 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 ap_compat.h file version. We maintain a comprehensive database of 100% malware-free ap_compat.h files for every applicable version of WampServer. Please follow the steps below to download and properly replace you file:

  3. Copy this file to the appropriate WampServer folder location:

    Windows 10: C:\wamp64\bin\apache\apache2.4.39\include\

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

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

Download ap_compat.h Files (Malware-Tested 100% Clean)

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