Windows 8 won't recognize USB driver for STM32F4 discovery (resolved)

I have a STM32-F4 discovery board, specific model ♯ STM32F407 VGT6. Having connected it to my computer via USB I have successfully run its test programs. Additionally I have successfully built a test program that came with IAR EWARM 6.5.

However, I notice that IAR, the ST Link Utility, etc. have been unable to download programs to the board. I noticed that the Devices & Printers section of the Control Panel recognizes my board but has a yellow icon under the device icon, with status ''needs troubleshooting'' and ''driver is unavailable'', despite having installed the USB driver and the STLINK driver showing up in the programs & features section of control panel.

(On edit) Eventually I got my board to work on my old computer that had windows 7.

Windows 8 won't load unsigned drivers without intervention

Already tried that twice, re installing driver under non enforcement mode, but the troubleshooting wizard from Devices & Printers still can't find the driver. Should I copy the STLinkUSBDriver.dll file to that Drivers folder in C:\Windows\system32 or someplace?

I'm using Keil 4.60, not IAR, but this did work for my Windows 8 install which up to that point wasn't working.

C:\Keil\ARM\STLink\USBDriver\ST-Link_V2_USBdriver.exe (3-21-12 8:59:18)

You might want to check if you have the most current firmware on the ST-LINK.

I don't think the system is going to entertain copying files into critical directories.

Upgraded the firmware, even dl'ed Keil 4.6, still no luck. Up to now I've never had USB issues with my computer, which I got for christmas and had win8 pre-installed.

1) Type devmgmt.msc in Search bar

2) Click on

Device Manager

3) on other device Click stm32 discovery for unlock and install device

that could be work.
