|Does this link help you?|
Your question is quite vague.
Here is what is on that page in the link:
When using QuickTime the following message may appear:
"QuickTime failed to initialize. Error # -2093. Please make sure QuickTime is properly installed on this computer."
The -2093 error may indicate the file 'QuickTime.qts' is missing, moved, or unusable. The QuickTime.qts file is usually located in the \WINDOWS\SYSTEM directory. To resolve this symptom, completely remove and reinstall QuickTime.
1. Download the latest version of the QuickTime installer.
2. Uninstall QuickTime using the "Add or Remove Programs" control panel. Make certain to click Uninstall Everything. See document 60342 "How to Uninstall QuickTime on a Windows PC" for more information.
3. Delete the contents of the Temp folder, C:\WINDOWS\TEMP (if it exists).
4. Install QuickTime using the version of the QuickTime you just downloaded.
5. Restart Windows.
