vipr [video image processing and relay] - Not working

MrMaarten's icon

I tried to use the VIPR external from http://ben.musicsmiths.us/vipr.phtml

but it doesn't work on windows 7 with Max 6.1.7
I get the error:

The program can’t start because avcodec-54.dll is missing from your computer. Try reinstalling the program to fix this problem.

Anybody know how to fix this?
