"CMSIS-DAP CDC" driver installation problem

[alsaleem00]

I am developing a code for RTL8710 Wifi module, cortex-M3. The toolchain/sdk requires OpenOCD/CMSIS-DAP to program the module. I have a STM32F103C8T6 board that I would like to make as CMSIS-DAP. I tried all firmware images in the firmware/stm32/hex, but still there is error when trying to update driver on windows 8.1

I already configured windows to "ignore" driver signing and restarted several times. I directed update driver update to folder that contains the "CMSIS_DAP.inf" file.

The drivers for this device are not installed. (Code 28) There are no compatible drivers for this device.

OpenOCD returns the following error

Error: CMSIS-DAP command CMD_INFO failed

Did I miss a step to install driver?

Thanks.
