SYMPTOMS
When you try to start Microsoft Age of Empires II: The Age of Kings, the program's &quot;Loading&quot; screen appears, after which the screen may turn black, and then the Microsoft Windows desktop appears.

The pre-game cinematic sequence is not displayed as expected, and you are unable to start the game.

When starting either version of Flight Simulator listed above, you may see the following message:

mmsystem006: There are no drivers installed on your system.



CAUSE
This behavior can occur when the Msvideo.dll Windows system file is missing or corrupted.



RESOLUTION
To resolve this issue, replace the Msvideo.dll file with a new copy from the Microsoft Windows CD-ROM. To do this, follow these steps:

Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.  Use a Windows startup disk to restart the computer to a command prompt. At the command prompt, type C:, and then press ENTER.

Note If Windows is not installed on drive C, substitute the correct drive letter. Type Rename C:\Windows\System\Msvideo.dll Msvideo.old, and then press ENTER. Extract a new copy of the Msvideo.dll file to the Windows\System folder.
