We used to post these offline standalone installer builds for various IM clients quite frequently but with us focusing more on the BitTorrent front this has died down a bit. To keep things moving and up to date, here’s the standalone, redistributable installer for the latest available build of Yahoo! Messenger. An advantage of downloading the full installer as opposed to the default over the web download provided by Yahoo! is that you can save the full setup to your hard disk and install it on as many machines, whenever, wherever you like. Note that this setup is not a hacked version nor a custom build. It’s provided by Yahoo! themselves – they just don’t show it on the default download page.
When you run the installer, make sure to install only what you need. By default the this setup comes bundled with a lot of unwanted crap (IMHO) such as Yahoo! browser toolbars and so on – the average user just needs the core IM program so we recommend you install just that without cluttering your system with other junk (unless you really need them of course).
