USB Blaster stopped working with Windows 10 update?

[Altera_Forum]

So it may be just a coincidence but last week everything was working good. On Friday my system updated with the latest Windows 10 1803 update and I noticed in Quartus ver 17.1 and the standalone programmer that i could no longer see the USB blaster. I tired another USB blaster and the same issue. The Device Manager shows the USB Blaster under the USB devices and says it's working normal. Thinking maybe i had a corrupted driver I uninstalled the driver and tried reinstalling the driver using the one that gets installed with the software and I got an error saying Windows has encountered a problem installing the driver, Access is denied. I am a full admin on this system so i don't feel "rights" is an issue. So i tried rebooting the computer and disables driver signature enforcement and that didn't help. I tired to uninstall the 1803 WIndows update but Windows came back saying that it can't be uninstalled. I downloaded the latest ver 18 standalone programmer and tried that driver and no change, same error.  

So wondering about admin rights i tried two other computers in my lab that had the 1803 update as well and I got the same problem tried to do a clean install of the USB blaster. I found one computer that was still at the Windows 10 1709 update and tried installing the driver. Here I got the issue where it tells me the hash for the file is not present, so i rebooted the computer and disables driver signature enforcement and was able to install the driver and reboot as normal with everything working. I'm on a domain so the computer has to be up to date so even rebuilding the computer and not do the 1803 update isn't an option. Anyone else have this issue?

If i load an old or new driver driver it see Altera USB Blaster but said it encountered a problem and may not work properly. Now that is where my issue is I can't install the driver without the Windows has encountered a problem error. So at this time it the device manager just see unknown USB Device. If say ok to the error it will seem like the driver is loaded but I still can't see the blaster in Quartus or the standalone programmer anymore.

I am having 1607 update so i couldn`t replicate the issue.  Best Regards Vikas Jathar  (This message was posted on behalf of Intel Corporation)
