Intel Indeo Video Codec missing on Windows 7 (64 bit)

I have tried to open a self recorded video with VirtualDub,
a Freeware Video Editing Software.

However, the video file was recorded by a camcorder using Intel Indeo
Video format, and VirtualDub was not able to open it.

I don't know whether the codec is supplied with Windows 7 or not, but
after installing the K-Lite Codec pack Standard from, it
still could not open the file properly.

It seems that the codec has to be registered in Windows seperately:
Start a command prompt as Administrator and change to the directory

Execute the following command:
regsvr32 ir50_32.dll

Now opening the file in VirtualDub should work.
