Internal Application Error With Windows Media Player
Internal Application Error With Windows Media Player
If you get an "Internal Application Error" while launching Windows Media Player it is likely not installed correctly. You will want to re-download a copy of the player and then install it over your installation. It can be downloaded at
Windows Media Player 9
It you are still getting the error after you know the player is installed properly then it is being caused by something external to Windows Media Player.
If you have installed any "Codec Packs" at any time they might also cause this. It doesn't matter if you have uninstalled it, because the uninstaller for these third party codec packs only work about 2% of the time. Go to your Device Manager:
• Double Click Audio Codecs and see the Properties Tab
• You can also run the Troubleshooter there
If it's not the player itself and you have not installed any codec packs at any point then the problem is most likely your video or audio drivers. To test this launch mplayer2.exe
• Start
• Run
• Type "mplayer2.exe" and see if you can play video and audio files without issues.
If you run into an problems then it's also likely causing issues with WMP 9 also. Reinstall both the audio and video drivers to fix that.
If that doesn't do it it's could be the CD-ROM driver doing it.
• Uncheck "Use Digital Playback" for that drive in WMP's Tools - Options:Devices menu
This is under
• Tools
• Options
• CD Audio on older versions of WMP.
• Your CD-ROM driver doesn't support this and does bad things when we try.
When you try to configure the direct memory access and programmed input/output (DMA/PIO) settings for a device on a Windows XP-based computer, the settings may not appear in the Properties dialog box for the device. Help does not provide the location of the settings.
• This occurs because the DMA/PIO settings are configured for each controller instead of for each device.
• To work around this issue, open Control Panel, and then follow these steps to configure the DMA/PIO settings for a controller:
1. Click Start, click Control Panel, and then click Performance and Maintenance.
2. Double-click Administrative Tools, and then click Computer Management.
3. Click System Tools, and then click Device Manager.
4. Expand IDE ATA/ATAPI Controllers.
5. Click the controller that you you want to configure DMA/PIO settings for.
6. Click the Advanced Settings tab.
7. In the Transfer Mode box, click either PIO Only or DMA if available.
• If that still doesn't help, go into your CD-ROM driver properties.
To get this, right-click on My Computer, select Properties, select Device Manager, select the "CD-ROM" or "DVD/CD-ROM drives" listing, select the drive in question, select Properties) and uncheck
"Use DMA" - and/or "Enable Digital Audio for this Device".
And you'd want to check with your provider for updated drivers even after this work-around. Microsoft has an article on further trouble-shooting here:
