Corrupt Hash USB Blaster Install

[Altera_Forum]

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!

you can go to device manager, right click and "update for driver software".  

Remember to tick delete existing file. Then map the same path for the driver C:\altera\11.1\quartus\drivers\USB-Blaster.  Or you can download the latest usb blaster here https://www.altera.com/support/support-resources/download/drivers/dri-index.html hope this helps.  (This message was posted on behalf of Intel Corporation)
