  • Error NET HELPMSG 3521 while checking the Update Service was stopped and the error code "8024000".

    Original title: error NET HELPMSG 3521 while checking the Update Service was stopped.

    Windows Vista. 32-bit, SP1 and 2

    Long story short, I tried to fix my problem of update windows since the beginning of July 2011.  My computer does not stop when you install updates automatically or manually.  I got a 8024000 error.  A shot an email to Ms support and I received an email quickly with some procedures to do.  I don't have to make these 4 days later.  Here is the part of the email.

    This problem may be caused by the following factors:

    1. the Windows Update service has stopped.

    2 corrupt Windows Update temporary files.

    3. bad Internet connection settings.

    4 corrupted DLL files.

    Step 1: Check the services concerned of the update of Windows

    1. click on the button 'Start' in the 'Search' bar type: "services.msc" (without the quotes) and press ENTER. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    2. double-click on the service "Windows Update".

    3. click on the 'general' tab. Make sure the "Startup Type" is "Automatic" or "manual". Then please click the button "Start" under "Status of Service" to start the service.

    4. repeat the above steps with the Background Intelligent Transfer Service (BITS).

    I completed this step.

    Step 2: Rename the folder C:\Windows\SoftwareDistribution Windows Update

    1. close all open windows.

    2. click on the "Start" button, click "All programs" and click on "Accessories".

    3. right click on "Command prompt" and click "run as Administrator".

    4. in the window "Administrator: command prompt", type "net stop WuAuServ" (without the quotes) and press ENTER.

    Make sure it is said that he has been arrested with success.  OK, it worked.

    5. click on the button 'Start' in the 'Search' box type "%windir%" (without the quotes) and press ENTER.

    6. in the opened folder, find the folder named "C:\Windows\SoftwareDistribution".

    7. right click on the folder, select Rename, and type "SDold" (without the quotes) to rename this folder.

    8. while still in the window "Administrator: command prompt", type the command "net start WuAuServ" (without the quotes) in the window to restart the service Windows updates

    It did not work.  I received a message...

    The syntax of the command is

    NET [accounts: computer: config: continue: file: Group: help: helpmsg: localgroup: pause: print: session: share: start: statistics: stop: time: use: user: view]

    C:\Windows\System32>_

    I tried again from the beginning and now get the following error: NET HELPMSG 3521

    "MS supports has not returned my emails to the technology or the Manager.

    Can someone help me?  Please notify.  Suzzz-Q

  • Error "Windows Media Player cannot play the file. The player might not support the file type or does not support the codec used to compress the file' when try to play wav or midi files.

    Original title: WMP "can't play wav or midi.

    Using WMP 11 on Windows XP SP3.

    Windows Media Player has somehow forgotten how to play wav or midi files. Doubleclicking either of these file types give an error "Windows Media Player cannot play the file. The player might not support the file type or does not support the codec used to compress the file. " There is a button 'Close' and 'Web Help' which still informs me, "you met the C00D1199 error message... ". ». Following the advice given nothing less than useful.

    I can easily play these files with RealPlayer or VLC so I don't think it's a driver problem, and it wasn't a corruption right after installing the other players. WMP seems to work OK when playing music or AVI. And there is no harm to hear a sound (wav or midi) in Windows for various system events. Have already uninstalled/reinstalled WMP without result.

    Thanks for your reply.

    I have since determeined the problem comes from an updated codec package I installed a few weeks ago. These codecs were from Shark007 which I believe is a Microsoft MVP. Use the codecs from this site for a number of years without any problems so I did not initially suspect it was the source of the problem. I uninstalled the codec pack and installed K-light package and everything seems to be Ok now. Now, I'll be in contact with the members of this forum.

    I am unable to play the video file and get the error "Windows Media Player cannot play the file because the required video codec is not installed on your computer."

    Can someone help me how to solve this problem. Thank you

    May be that the video file format is not compatible with Windows Media Player.

    Options: -.

    1] download and install VLC Player. It's free and supports file formats more than WMP.

    2] download and install the codecs

    Personally, I prefer VLC Player-if you have that then not need to download and install the codec of any third party.
