Yea, it works on my x64 Windows 7 Pro system. However, it has some weird behaviors. First of all, the "64-bit version for Windows 7" installs into the x86 folder. Ok...? Additionally, after pinning it to the taskbar, when you open it, it creates yet another icon on the task bar as the anchor, rather than using the permanently anchored icon that has been pinned, like the rest of the programs on the task bar.
Just a bit of weirdness going on there. Maybe it's just me.
