32-Bit and 64-Bit
AMD APP SDK 3.0 for 32-bit and 64-bit Windows®
link (3rd row down) from http://developer.amd.com/amd-accelerated-parallel-processing-app-sdk/ should work. The installer version is the same as the one I've been using, but it has a (1) before the file extension at the end. I already have it installed but can try on a new computer tomorrow if it helps any.
Thanks for reporting it. I also observed same problem when tried those links. I'll report it to the concerned team. Hope it's a temporary problem and will be resolved soon.
As a workaround, I've sent a temporary download link via PM. Please check your inbox.
