I've bought about a month ago a logitech g19 keyboard. When i downloaded the driver (and software) from logitech support site, i had to chose Windows 7 64. When i started the installation a windows popped up, and said: this installation is not compatible with your operating system. the same result was on windows 7 compatibility mode. I installed windows 7 back, but i started to miss windows 8, and thought that if anyone of you can help me?

welll... the keyboard works with W8 but the lcd, lights, macros, media keys, volume, usbs and the lock switch does not work with it... maybe the driver installer can be opened with 7z

The g19 keyboard is a new one, i think tha tit was released in 2011. and it's the keyboard on logitech gaming set.
so, i'm sure that they will release a driver after w8 comes out, but it's still a half year to wait...

Some updates: It seems, that if you download the gamepanel software, it will automatically download and install the drivers (whitout os check ) it works fine.

I have to set up my game first. Plug in the keyboard with the mains which for some reason locks up the start and options menu's. Works a treat till i quit the game, then i have to unplug the mains to get my menu's back. Hope there's a fix soon, as you know if you have one, without light the letters are dark and opaque.
