I havent seen any solution or explanation or info about it, but i fear you need to move to 64-bit. The percentage of 32-bit users in the world is shrinking, so i dont think they can afford to keep build an extra client and support it. maybe later when its more stable and they dont need to patch/hotfix so often as they do now? Hope iam wrong for your sake though, or that you got a 64-bit windows somewhere and can reinstall.
