Remember to download programs supporting MP4B files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of QuickTime Player with MP4B files

If the application is or has been freshly installed, but the MP4B file still does not use the QuickTime Player program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the MP4B file with the QuickTime Player application.

Step 3. Update QuickTime Player to the latest version

If, however, after binding QuickTime Player with MPEG-4 Audio Layer Bookmarkable there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Apple, Inc. page and install.

Step 4. Check for the following problems with the MP4B file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The MP4B file may be unusually small compared to the original file. This is most often caused by a problem while downloading the MP4B file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our MP4B file. As a result of the scan, sometimes it is not possible to recover MP4B files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of MP4B file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular MP4B file corruption. You can restore the file from a backup or use Apple, Inc. help.
The program indicates that the file is encrypted or corrupted. The encrypted MP4B files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. It is best to move MP4B to a different directory.
This problem usually affects more complex files. In this case, the MP4B file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the MP4B file for a certain period of time. If nothing helps, please reset the device.
