Corrupt Hash USB Blaster Install

I ran into a strange issue when trying to install USB Blaster on the computers at my school (Yes, I had an administrator enter their password so I could make changes).

I went through the same process I did on my home computer to install the driver, Device Manager --> Other devices --> USB Blaster/properties --> Update driver --> Browse my computer for driver software --> then selected C:\altera\11.1\quartus\drivers\USB-Blaster

It worked on my home computer, but on these 6 computers, each of them found the driver, but could not install due to

some Corrupted Hash file. (sorry, I don't have the error message on hand)

Has anyone else encountered this issue? :confused:

Thanks in advance!
