SYMPTOMS
After you install Windows Media Player 7, when you attempt to play a QuickTime file, the file may be opened in Windows Media Player 6.4.



CAUSE
This behavior can occur because .qt and .mov files are not associated with Windows Media Player 7.



RESOLUTION
To associate QuickTime files that have .qt and .mov extensions using Windows Millennium Edition (Me), follow these steps:
 * 1) Double-click My Computer.
 * 2) On the Tools menu, click Folder Options.
 * 3) Click the File Types tab.
 * 4) In the Registered file types list, click QT, and then click Change.
 * 5) Click Microsoft Windows Media Player, and then click OK.
 * 6) Repeat the procedure for .mov files. (Click MOV in the Registered file types list.)

To associate QuickTime files that have .qt and .mov extensions using Windows 98 or Windows 98 Second Edition, follow these steps:
 * 1) Double-click My Computer.
 * 2) On the View menu, click Folder Options.
 * 3) Click the File Types tab.
 * 4) In the Registered file types list, click QT (this extension is generally found under &quot;Video Clip&quot;).
 * 5) Click Open, and then click the Edit button.
 * 6) Click the Browse button, browse to the C:\Program Files\Windows Media Player folder, click Wmplayer.exe, and then click Open.
 * 7) Click OK, click Close, and then click Close again.
 * 8) Repeat steps four through seven, but click Play instead of Open in step five.
 * 9) Repeat this procedure for .mov files.

NOTE: This procedure associates all .qt and .mov file types with Windows Media Player.



STATUS
This behavior is by design.



MORE INFORMATION
This behavior occurs because Windows Media Player 7 does not support files that are created with QuickTime version 2.0 and later. File formats from QuickTime version 2.0 and earlier are supported in Windows Media Player 7 only if you have upgraded from a previous version of Windows Media Player. If you have not previously installed Windows Media Player, Windows Media Player 7 does not support the playback of QuickTime files.
