USB Drvers not working with Quartus 16.0 in Windows 7

--- Quote Start ---

I recently installed Quartus 16.0 on my Windows 7 Computer and unistalled Quartus 15.1. When I went to run SignalTAP, I get:No device selected

andInvalid JTAG configuration

even after I have selected USB-Blaster

I have tried two different US- Blaster cables.

When I check the device driver status, I get:

This device is working properly.

When I check the Driver File Details I get:

C:\Windows\system32\drivers\usbblstr.sys

C:\Windows\system32\usbblstr32.dll

C:\Windows\system32\usbblstrlang.dll

C:\Windows\ststem32\usbblstrui.dll

C:\Windows\syswow64\usbblstr2.dll

I uninstalled the river and re-installed it by plugging in the USB Blaster and go the same result

Any suggestions?

I'm having the same issue.

It's very weird, because the JTAG programmer works fine. I have tried two brand-new USB-Blaster IIs with this.

It's even weirder, because this morning SignalTap II was working, then I made a change to the design, and now it doesn't.

Another detail. In the SignalTap II GUI, in the JTAG Chain Configuration window, in the Hardware box I see my USB-BlasterII recognized. I can scan the JTAG chain, too, and it finds the FPGA (a Cyclone V). Attempting to program the device results in the "Invalid JTAG configuration" error. Now when I click the "Setup ..." box in the JTAG Chain Configuration, in the Hardware Settings tab for "currently selected hardware" I see "No Hardware" chosen. I pull that down and select the USB Blaster II and click close. Again, I try to program the device and get the same "Invalid JTAG configuration" error.

But back in the Programmer program (only one is open at a time), if I click the "Hardware Setup" button, the same hardware select dialog pops up as in SignalTap II, only this time "Currently selected hardware" is my USB-BlasterII," not "No Hardware."

So there is something screwy going on with how SignalTap II chooses the JTAG hardware.

I uninstalled the drivers, downloaded the stand alone programmer, installed it as administrator, and cycled power. Now Signal Tap works.

I remember now that when I installed Orcad many jobs ago the installation instructions said to Install as Administrator.

Perhaps ALTERA should add that to its install instructions
