Hello, I was on an official hands-on ST32M workshop on 2013-03-07, by ST & Arrow.
a) The free edition of the Keil uVision IDE still suggests to be installed at c:\Keil.
With Win7 and Win8, it's the best to install the uVision IDE ( on 32 Bit Windows ) at C:\Program Files\Keil
b) More important, the ST-Link debugger driver shipped with the Keil uVision IDE 4.70a does not install on Win8 :-(, while it was possible to install it on Win7 ( on 32 Bit Windows 7 Pro).
Still after install, Win8 does handle the driver for the ST-Link USB device as "not properly installed" in the Win8 device manager :-(. With Win7 everything works fine...
Sincerely Rolf
and allowed to configure it and make use of it as you feel best suits your needs.
you, yourself, do not know what you want, be happy someone in Redmond does.
