Hello. It looks like wixelconfig.exe is not found on your computer's PATH. If you have not already, please install the Wixel Windows Drivers and Software, which can be found on the Resources tab of the Wixel product page. Also, please try restarting your computer. If this does not help, please run
echo %PATH% and post the output of that command here so we can make sure that the Wixel programs are on your PATH.
