How To Fix The C00D11B1 Error
To resolve the issue, it is important that you determine the causes first and then do the necessary steps to address them.

To do this, you may either remove it via the safe mode or you may utilize a program such as an automated tool to automatically remove it from your system. To use the safe mode, the first step is to reboot your PC and then follow these steps:
- Before windows loads up, press F8 repeatedly until you can see on your screen a menu display.
- After that, you have to choose “Safe Mode” and then click “Enter”. Next you have to locate “Start” and then press “Run”.
- On the run box, type “appwiz.cpl” and then click “OK”.
- You can proceed by locating “Windows Media Player Program” followed by pressing “Remove”.
- A series of instructions will then pop up and you have to do what is prompted.
- After completing the process, restart your PC. This will remove your Windows Media Player from your system.
The problem can also be fixed by making sure you have the correct proxy settings for Windows Media Player. The proxy settings ensure that the Windows Media server can establish the best possible connection to the Player depending on the environment. The Player is designed to automatically receive streams from different protocols. However, it is probable that your settings are incorrect and you have to check if you have the appropriate configuration. This can specifically be done by changing the UDP settings of Windows Media Player.
The final step is to download and run a registry cleaning tool in your computer to remove the corrupted files in your system including the damaged codec files. The highly recommended tool is the “Frontline Registry Cleaner” which had been proven to be very effective in removing junk files and errors in your PC.
