8.1 x64 Pro here. Tried RC2 and RC1. Neither work. I donated a moment ago but that's irrelevant. Installed Debugging Tools and got my symbols. Copied them into the directory of course. Debug.log says: [2013-12-14 15:16:32][Thread 0xB48] Hook (USER32.dll!CreateWindowExW from shell32.dll) installed[2013-12-14 15:16:32][Thread 0xB48] Hook (USER32.dll!SetWindowCompositionAttribute from explorer.exe) installed[2013-12-14 15:16:32][Thread 0xB48] Hook (dwmapi.dll!DwmEnableBlurBehindWindow from explorer.exe) installed[2013-12-14 15:16:32][Thread 0xB48] Hook (USER32.dll!LoadImageW from themecpl.dll) installedaerohost.exe is running but there's no command dialog or watermark.
