FAQs & Troubleshooting

When I install the drivers, Norton AntiVirus displays a Security Alert that a medium risk application "[file name].exe is attempting to connect to a DNS server".

 

 

The name of the application file (.exe) displayed on an alert window is a Microsoft® file necessary for the driver installation. The file name will vary depending on how you are installing the driver. It can be "_is*.exe" (* is a variable), "Setup.exe" or "DPInst.exe".
Select Always block connections from this program on all ports (Recommended) and click OK.
