Fix: Cannot Play. This File Isn’t Playable. 0xc10100bf Error In Windows 11/10

While playing MP4 video files on your system, you may sometimes come across the “Can’t play. This file isn’t playable. 0xc10100bf” error in your Windows 10 PC. This prevents you from playing the MP4 video files on your PC, especially using WMP (Windows Media Player) or the Movies & TV program. This error usually occurs when the video is corrupt, has the wrong file extension or your media player does not support its format.

While there can be different reasons why you may encounter the “Can’t play. This file isn’t playable. 0xc10100bf” error on your PC, some of the major reasons include:

  • When the video file is corrupted;
  • When the file format of the video is not compatible with the media player (Windows Media Player/Movies & TV app);
  • When the video file is using the incorrect file extension;
  • When the video file somehow gets damaged during the transfer;
  • When the video file is downloaded from an unverified source or if it’s infected by a malware. This ends up corrupting the video file.

This error mostly occurs with different video formats like MP4, AVI, MKV and MOV.

How to Prevent the 0xc10100bf  Error

Here are some tips to prevent the 0xc10100bf video error on your Windows 10 PC.

  • If the error occurs because you are playing the files using an external driver, transfer the files to your PC’s local drive.
  • Make sure that you have installed all the pending Windows Update to ensure that video plays uninterrupted.
  • Download the video files from a trusted website, preferably from of the official website of the video maker or a trusted video software.
  • Moreover, using a good quality and reliable anti-virus software is also important to keep your system protected from virus and malware.

Fortunately, there are a few solutions available that may help fix the issue. Let’s see how:


Method 1: Basic Troubleshooting


  • When you come across the “Can’t play. This file isn’t playable. 0xc10100bf” error, the first thing you must try is to play the MP4 video on another computer and see if it’s playing on that. A lot of times, this method helps fix the damaged file issue and then you can continue to play your video files as usual on all devices.
  • However, if this does not help, you can also try playing the MP4 files using a different drive than what you are using now. For example, if you are using an USB drive, you can replace it with another external drive. It may be possible that the USB drive is corrupted and hence, unable to play your files.
  • If that doesn’t work, then you can copy the video file individually from the USB device. This is because, sometimes, when you try to copy all the files together from the device to your PC, chances are, that the files may get damaged during the transfer. Hence, transferring the files one by one may help fix the issue.
  • Additionally, you must also check if the video file format is supported by your media player, such as with WMP, Movies and TV applications, etc. If the file format is not compatible then try converting it to a supported format and for this, you may try using any trusted free video converter software.
  • Check if the video file ahs the correct extension because if it’s an incorrect extension it may generate the 0xc10100bf error. This usually happens if you have renamed the file without using a reliable video converter.
  • Alternatively, you may also try downloading the same MP4 file again because sometimes the download may get aborted before the download is complete. Simply return to the source website and click on the download link again to re-download the MP4 file.
  • You can also try uninstalling and re-installing the program that’s throwing the error and this may fix the issue sometimes.
  • Make sure that you also run a scan using a 3rd party antivirus software or the Windows Defender (built-in Windows security) to remove any malware or virus.
