asus intel extreme tuning utility not starting

You are running a non-standard version of Windows on the G750, there is no Windows 7 support, so you might be missing software that supports the Intel XTU - you could try downloading all the Windows 7 related drivers from Intel and see if that helps too. Try uninstalling from the uninstall control panel, reboot, and then install the latest version 4.3.0.11:

You might have installed an old version first, and if you didn't do an uninstall before installing the correct newest version there might be old stuff hanging around. Has this problem happened to anyone else? Only the black window with 'Intel Extreme Tuning Utility' comes up and it will sit there for a few minutes before an error box comes up stating that PerfTune has stopped working (or something like that). I believe I've downloaded the right version, seems pretty straight forward (windows 7 64 bit), but the program will not start. Recently I opted to try again, and I'm still not having success, but now I can't even get THAT far. Last month, I was able to physically get it to start, but the UI was pretty much blank with no tuning options. To put it simply, I cannot get this thing to work.
