Issues with camera displaying (Windows 7)

I ordered a camera off of Amazon and have been trying to figure out how to make it display on the software. I know about having to update the UVC drivers since that seems to be everyone else’s fix. I’m confused on how to install them, or they don’t work for me. The camera displays fine when I check it online. I’ve tried the Lenovo USB drivers online, which made it display, but now it’s just a black screen on the program. I’ve also tried switching from default to custom, as well as read all the other forums. Even if someone could explain how to install the drivers, it might help because I believe I may be doing it wrong as well. Any guidance would be much appreciated. I’m considered a noob to all of this! TYIA.
