I just added 64 bit windows versions of the apps; your clients should eventually pick up the change if they haven't already. I've been testing them for the last couple days on my machine, so they should be good, but I'll keep an eye on them just to be safe.

These versions provide some speed improvement over their 32 bit counterparts, especially with the longer running WUs (those over ~1 hour). In some of the longer cases, the 64 bit version is almost twice as fast.
