    Windows 7 don’t allow 3rd party codecs? Oh, I never observed that as I have been using VLC for two or three months. I stopped using these codecs as they messed my system once. This tool can be very useful for those who use codec packs like K-lite, Colec etc.

    Hi, thanks for this tool. I tried again and again, but it only lets me run the ffdshow video codec, while I’m mostly interested in running the audio codec. Any tip on how to do this? Thanks
