I have that same version of SXi installed. I'm trying to get it to recognize the SX485J chip in the Vicious Ant and apparently don't have the correct driver installed. When I plug in the VA it plays the wave file telling me I've plugged in a USB device but I get a bang in Device Manager saying the it's an unknown USB device and that the device descriptor request failed. I can't find drivers for the SX485j chip on Yihi's site.
In the startup menu there is an SXi folder containing an app named SXi Driverstartup. It will open and present a window to click Start; Task Manager shows "Device upgrade and control GUI tool (32 bit)" running but almost no CPU usage, so not sure what it's doing. Never finishes.
If I click on Connection in the SXi app, I get "Device not found". If click on "Install Driver" (with the VA connected) is fails with "The driver installation failed".
App doesn't see the chipset and the driver won't install.
