Where to install to?

Where do you install codecs to? To a specific program? And if so what file in the program? Or to its own program file?? Thanks.

when you install codecs, they’re installed into your system files and registry, you don’t pick “where” to install them, you just run the installer and youre good to go

Thanks for the quick reply. I ran GSPOT and it shows a lot of codecs in various places.
I suppose what ever needs them to play/sound/video knows where to look?

I have had some errors requesting TAG 1879 and 2000. I have looked for them on web but can get info but haven’t found them. Any suggestions?
