Wow, thanks for all the responses guys. Strollin, it was a video driver
.exe. There was no .zip version of the file available (at least, I didn't see one, even though there normally is), and I couldn't install it with a .exe version because my laptop is a Dell, and it only accepts Dell drivers
despite those being much older than the Intel ones. They must be installed manually.
Anyway, WinRar was able to do it. I could have sworn there was a way to do it via the command prompt, though. Thank you for your help everyone :]
