New computer. How do I access previou yahoo IM

Check your new computer first and familiarize yourself with all the apps that are on it. YIM may already be installed. If not, you will need to install it.

Download YIM

I don't think so but my answer is no but if u download it on your old computer yes but if u didn't download it on your old computer it is sepuse to work becouse your yahoo account is on a yahoo server it have's it's own information so it,it is even sepuse to work on your friend or someown's computer sorry for my spelling i hope i was usefull i tried my best.
