  • Quick Time Player does not work in El Capitan

    Now Quick Time Player does not work properly.  When I click to use it, the only thing it allows me to do is 'click to drag', while he was recording a screen, buttons disappear and the only way I can stop the recording is to go to the menu screen and exit the Quick Time Player.  So annoying!

    It also is not allowing me to change.  When I try to edit my videos and then save it, it says that it cannot save the file.

    None of this makes no sense at all.

  • Quick time player does not work

    I used to be able to download videos from my camera in my photo folder and play.  Now, when I click on one, all I get is an error message telling me to download Apple Application Support.  When I try to do all I get is something called driver Detectivemc which begins to be free, but all of a sudden, you have to pay for it.  What is the problem.  When I click on the Quick Time Player icon on my desktop, I get the same message.  I can't find how to upgrade all the drivers without having to pay for them.  Please help me.  Oh yes, using Windows Explorer, Vista Home premium.



    You can try to download and use this program to uninstall third party to remove the detective driver. Revo uninstaller pro offers a free 30 day trial.

    Hope it will be useful.

  • Media Player will not play wav file

    I use Windows XP Home Edition and Windows Media Player 11.  It will not play a WAV file.  He returned with the message "Windows Media Player encountered an error when reading the file."  WAV files are on a CD.  If I put this CD in another computer which has XP and the same version of WMP, it works very well.  I am able to play audio CDs and MP3s, but not WAV files.  Help!

    Hi just to be sure, have you checked library "all file types" / more options / file types

  • Media Player will not play music files now that he used to play.

    I have Windows Vista and my media player has recently decided that it will not play some music files that it used to play. When I try to read, I got the error message saying that the file type is not supported by the player, or that the file was compressed by using a codec that does not support the player. Why has it started to do this, and what can I do about it? He is not doing it with all the music files, only some of them.


    The ASF Format (Advanced Systems) is the preferred Windows Media file format. With Windows Media Player, if the appropriate codecs are installed on your computer, you can play audio content, video content, or both, that is compressed with a wide variety of codecs and that is stored in an .asf file.

    You can check the link below for more information on the types of media files that supports Windows Media Player

  • Windows Media Player will not play music files - need to reset the file path

    I'm trying to access my music on an external drive (g) using windows media player. The player is looking for music in the E: drive, which is a separate external drive that my friend uses for its iTunes. How to reset the path to the file for windows media player? It gives me the possibility of rerouting individually paths files, but not a lot of re - routing. I have reset the default settings, reinstalled the drive external, even enabled/activated on WMP (of the Panel).

    I tried. The drive G:\ was included in the WMP library before this problem (and to make sure, I deleted and added it). Despite this, the paths for each song pointed toward the drive E:\.  I solved the problem by deleting all of your WMP library (not files) and restart the media player. The files were then reread with the correct file paths.

  • Windows Media Player will not play the .mp4 files after installation IE10 - BEX error message

    Hello! Recently, when I tried to read a file .mp4 on Windows Media Player, the player would immediately stop working and tell me that he could not play this type of file, even if the day before he could do so without any problem. I had an option to close the program or click to more information, so when I clicked for more information, he gave me this:

    Back to a system restore point previous fixed the problem and I could again play the files in Media Player, but during the night that Windows updates installed and the morning I could not play these .mp4 files once more. So I restored to a point earlier, changed my updates so that they are is more automatic and by installing each day at a time, I finally isolated the problem in Internet Explorer 10. If I install that, just Windows Media Player will not play these files.
    I tried a manual update of Internet Explorer 10, turn off all the options of toolbars shit and everything, thinking that when it automatically installs those who may be included, but that has not helped. Had to go back to my previous IE10 restore point. So no matter what, Internet Explorer 10 kills my ability to play .mp4 on Windows Media Player files.
    I don't have toolbars running on IE9 at all.
    I know that's obvious answer is 'do not install Internet Explorer 10' or if I do, download another player for .mp4 files. But the fact is, it shouldn't happen, it is indicative of something being wrong, and I would like TO be able to install Internet Explorer 10 AND use Windows Media Player to play these files. If someone else has had this problem, or know a way to fix it?
    Here are my system specs:
    Windows 7 Ultimate 64 bit
    Intel Core i5 - 3350P @ 3.10 GHz CPU
    ASRock H77M LGA 1155 motherboard
    8 GB DDR3 240 - Pin SD RAM
    Diamond Radeon HD 7870PE52GV 7870 GHz video card
    And all my programs are installed on this:
    SAMSUNG series Pro 840 MZ-7PD256BW 2.5 "256GB SATA III MLC internal Solid State Drive
    I'd appreciate any help you can provide! Thank you!!
    It sounds like your question. I think you should uninstall this update and
    hide and see if that solves your problem. Please report.

    I tried myself after experiencing the same problem and error code. I uninstalled the KB2670838 update, and then my Windows Media Player finally worked again. I also found that IE 10 must be uninstalled as well. Installation of IE 10 also automatically installs the update of KB2670838 platform. After uninstalling KB2670838, IE 10 automatically uninstall with it, better you hide two updates so that they do not install again. From the link in the previous post, I learned that the platform update is having problems of conflict with the AMD drivers. Good luck to you and hope this helps.

  • Media Player does not play the .m4a file

    I just want to know why my player will not play a file. The file says it's a media player .m4a... I tried to download a recent version of the player, but he said that I had a newer version of it and it wouldn't download. So if I have a new or updated version of the player, why used it play the file?

    Windows Media Player uses the codecs to understand file formats. A codec is software that includes a particular file format. You will need to install a codec.

    If you click Help on the Web in the dialog box it would have been explained to you.

    Also if you let Windows search for the appropriate program when dbl clicking the file it'll tell you what it is and what it can play.

  • Media Player will not play mp4 or mpeg1 files. When I try the system crashes and it goes to the blue screen of death

    I'm running a quad core with 8 GB of windows 7 with office 2013 RAM.  All are clean installs.  When I try to play a video file on Media player my system breaks down and made a memory dump.  This also happens when I try and put a video in PowerPoint.  I am able to play these videos on QuickTime on the same machine.  The videos play fine on another machine of Windows 7 office 2013.  We use this system for presentations churches.

    Can anyone help?


    1. Do you have an error message when you play this video?
    2. What Media Player do you use?
    3. Did you recent hardware or changes to the software to the computer before the show?

    I suggest using Windows Media Player, then try the following steps. This problem may occur because of codecs. A codec is a software to compress or decompress a digital media file, such as a song or a video. Windows Media Player and other programs use codecs to play and create digital media files.

    You can refer to the suggestion made by Rohit Chettri in the following link and check if it helps.
