FTB_Launcher.exe (and maybe the .jar) fails to work on Windows 8

It turns out that Windows 8 and FTB_Launcher.exe can't properly together. This gives a small error(too small for an error report, something like "failed to install modpack"). Running the .exe with compatibility mode seems to be working.

Work fine for me, dosn't seem like a Win8 issue
