remove and reinstall the vda

Alternative?

You could try doing just a repair. But the uninstall and reinstall is pretty harmless. I do it all the time when things break it, like visual c++

What I mean is that when I have to do the script for this USB device, I cant have part of the script be "repair" the VDA.....For obvious reasons, one being that the VDA requires a reboot and would cut all connections

You would want/need to drain users off the VDA prior to repairing it. If the VDA isn't fully operational it's best to get users off
