Regarding this problem, I strongly suggest that you don't try downloading the missing file from the Internet and then copy it to the location. By doing this, you probably will get infected with malware and viruses. To fix it, try reinstalling the driver for your Idea Netsetter. You can find it on the following website. Also, in this matter, it's advised to use a cleaning utility like Malwarebytes to make sure that your computer is safe. You can also use an antivirus program.
