Application Error in Windows Movie Maker

Windows Movie Maker
Microsoft replaced Windows Movie Maker with the enhanced Windows Live Movie Maker program when it launched the Windows 7 operating system. Windows Movie Maker came as a standard feature with the earlier Windows Me, Vista and XP operating systems. All versions of the software allow users to create and edit movie files from video clips, audio files and images stored in the computer’s library folders.
Application Error
The applicator error in Windows Movie Maker prevents the program from starting and displays the “Windows Movie Maker Has Stopped Working” error message. Microsoft reports that the application error occurs on Windows Vista computers running Windows Movie Maker. The issue doesn’t occur on Windows XP computers, or on the newer Windows Live Movie Maker program running on Windows 7 systems. The problem arises when an incompatible video filter is installed on the computer.
Video Filters
Windows Movie Maker uses the video filters and codecs installed on the computer system to read video files in different formats, such as AVI, MPG and WMV, and to process and enhance video footage. Installed third-party graphics and video programs typically include a selection of associated video filters and codecs. Some file-sharing programs also include video filter and codec packs. The application error can occur if Windows Movie Maker isn’t compatible with any of these third-party video filters. The problems with Movie Maker might start soon after you install another video or graphics program, or download a codec and video filter pack.
Troubleshooting
Microsoft recommends troubleshooting the problem by starting Movie Maker in Safe mode and removing third-party video filters. Click 'Start | All Programs | Accessories | Command Prompt.” Type “CD \program files\movie maker” into the input field and press “Enter.” Type “moviemk.exe /safemode” and press “Enter” again to launch Movie Maker in Safe mode. Click “Tools” in the Movie Maker navigation menu, select “Options” and click the “Compatibility” tab. Click to clear the check boxes next to all third-party video filters in the Filters section. When you relaunch Movie Maker in normal mode, the program should work correctly.
