Windows 7 unable to find COM driver for USB-KW24D512 using example SMAC Connectivity Test

I have a USB-KW24D512, using it on a Windows 7 64-bit and I have programmed it with the example SMAC Connectivity Test(USB-KW24D512_SMAC_Connectivity Test.srec) which I should be able to connect through a COM port. I'm getting a issue where Windows is unable to load the correct driver, using Update Drivers and manually selecting the path to search, ( C:\Program Files (x86)\Freescale\Drivers\ ), it is not finding it. There is a installer in the C:\Program Files (x86)\Freescale\Drivers\USB-KW24D512 directory, dpinst64.exe, which I have successfully installed. But Windows 7's device manager is still showing it as drivers for this device are NOT installed for the FREESCALE VIRTUAL COM.

Device: USB-KW24D512

OS: Windows 7 Enterprise 64-bit

If you need more information, let me know. How do I fix this?

Thank you

I figured out the issue, it appears the drivers included with the BeeKit installer ( C:\Program Files (x86)\Freescale\Drivers\USB-KW24D512 ) are a older version and Windows 7 doesn't accept them. If you download the USB-KW24D512 Board Support Package and Browse to the Drivers directory where it is installed and point it at the Drivers directory, it will instsall correctly and then work as expected. I was then able to connect the HyperTerminal to it and get the Connectivity Test menu and interact with it.

The BeeKit installed "fsl_ucwnt.inf"

The Support Package installed "fsl_ucwxp.inf"
