They work under Win XP 64-bit fine, and clearly you have it working on Win 7 X64 Ultimate (I'm using enterprise). I'm beginning to suspect it might be something to do with the C++ Redistributables? The crash when it loads really reminds me of that sort of crash, when you download a redistributable that gets called by something, and it's not the right 'year' of redistributable. Anyway, I'm really enjoying the work you've put into these on the other systems I have, and if I discover any information about what's messing it up, I'll let you know.
