Although the following tips are related to Microsoft Windows and PC hardware/software configuration, these steps may help to resolve issues.
* Make sure your computer meets the system requirements outlined at http://www.apple.com/quicktime/download/requirements.html
* Try running ScanDisk to verify that the directory is OK. This is an important step to take before installing any software.
* Try running the stand-alone version of the QuickTime installer in "Safe Mode." It is available at http://www.apple.com/quicktime/download/ . This can help to isolate issues with background applications, and some driver conflicts.
* Make certain you have installed the most recent drivers for your sound and video cards. Even if you have a "brand new" computer, it is not guaranteed to have the most recent software installed. Contact the manufacturer of your sound and video cards for additional information.
* Make certain you have installed a recent version of DirectX. This can be downloaded from http://www.microsoft.com/directx/. Errors are usually related to software conflicts, unusable files, or incompatibilities. They can also be related to specific hardware combinations, and sometimes the way in which the hardware is configured. Keep in mind that an error message does not necessarily point to a particular cause or solution. Since there can be many different causes for a particular symptom, some suggestions may not work, and you may need to discover a solution on your own.
Note: Please contact Microsoft Corporation for help configuring Microsoft Windows.
