What are webcontroller.xml Error Messages?


General webcontroller.xml Runtime Errors

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

Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\Program Files (x86)\Steam\tenfoot\resource\layout\webbrowser\webcontroller.xml

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


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

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

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


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