Move along, it still says release candidate on the page.
I don't know why..last night i download it from the same link and Microsoft have changed it to IE8...BTW if you still want to download ..Here is the Exact link direct you to IE9:
If it can ever work, I tried to install on a 64-bit machine and it consistently failed no matter what I did...then finally what I did?...gave up! Will wait for IE10, if it can install at least :)
it doesn't work on XP...and i have personally download IE9 and working smooth like butter and also it's fast!
