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
I have the Keil tools under c:\keil\
Most other tools gets installed in subdirectories under c:\bin\
And I keep lots of documents under c:\doc\ instead of merging them into the M$-defined messy "My Documents"
Micro$oft have somewhere down the line made the decision that we don't own our computers and have to be protected from ourselves.
