Unable to share Iphone 7 4G connection with computer

[theereal]

At my work, our current computer situation leaves us without cables for a few weeks, and its an old windows 7 desktop computer. It doesent have wifi so i bought a wifi usb dongle to temporarily remedy the situation. But i needed to install the drivers for the dongle on the computer, which requires and internet connection, so i attempted to connect my iphone 7 to the computer using an iphone charger and share my 4g to get the drivers installed, but when i shared the internet via tethering (following instructions found on google) the computer did not find my iphone 7 as an option to connect. I attempted several times. Any ideas?
