I can't seem to get "stm32f10x_stdperiph_lib_um.chm" working.
It turns out that the "stm32f10x_stdperiph_lib_um.chm" file from ST-Microelectronics must be in a directory without spaces in it in order for it to work. ...on the Windows7 platform.
I put it in the root directory, and it worked:
C:\stm32f10x_stdperiph_lib_um.chm
and made a short-cut to it.
I thought others who use the STM32 running on Windows7 might want to know this: hence, I posted the mini-solution
