Pardon my ignorance, but can someone tell me where I extract the above download to - what path and destination do I follow?Many thanks

Hi,I think http://www.guru3d.com/files/ will be a good place to start with.hm (a DC3 AND Mig21 lover)

Yes I have already downloaded this but where do I extract it to???What is the destination on the hard drive?

You could create a new folder somwhere you can find it again, name it riva tuner or something like that, and extract it into that folder.S.Jensen
