This is frustrating, i know.
try this:
-uninstall the TI
-unplug your TI from the USB cable
-try to reinstall without the TI connected
if the above doesnt work:
-go into control panel and click "show hidden drivers"
-find the TI Audio under "sound" and remove that
try again.
also try changing your USB ports and cable.
this has worked for others.
