You can try this thread
as it has a variety of fixes and workarounds, depending on your comfort level. I don't have Win8 myself so I can't really vouch for any of it. Sorry.
However, one thing confuses me. You say you have a "32bit x64 system" in your post? But that would seem to be contradictory to me, as it implies you have a 32-bit and 64-bit system at once. Did you mean x86 perhaps?
