Hello,

when i try using the STM32 Discovery board (STM32F100)

with Keil uVision (V4.20.03.0, Target DLL: STLink\ST-LINKIII-KEIL.dll V1.5.6), when i try to debug or flash there always pops up this error:

''Failure loading STLinkUSBDriver.dll''.

This Dll exists in the path C:\Keil\ARM\STLink\,

but it just does not want to work.

Any help is appreciated.

HI Steahler,

My solution of problem:

Uninstall from Windows STLINK V2 soft, bacause this new STM32 ST-LINK Utility did not connects to my VLDISCOVERY. I'am happy did not delete older file um0892.zip (downloaded before 2011 March 18). After installing this older ST-LINK software I was able to connect to my VLDISCOVERY. To be happy with Keil environment : rename C:\Keil\ARM\STLink\STLinkUSBDriver.dll to ''..too_new...'' and copy older

STLinkUSBDriver

.dll (2008.09.24) to this directory from C:\Program Files\STMicroelectronics\STM32 ST-LINK Utility_old\ST-LINK Utility. You must be Windows Administrator group member to use ST-Link with Keil. This will not depend on language settings.
