I'm trying to get BenchVue 2017 working with my MSOS404A on a Windows 10 machine. The scope is successfully detected in Keysight Connection Expert, but when I go to launch BenchVue, the splash screen comes up... then nothing happens. I also changed the permissions to C:\ProgramData\Keysight to full access for everyone and that didn't help.
I also ran the BenchVue Troubleshooting Wizard:
Whenever an instrument connects in Connection Expert but not BenchVue, immediately suspect corrupt VISA libraries. This often happens if both Keysight and NI IO Libs are present. I’d first suggest uninstalling VISA Shared Components, then doing a “Repair” on Keysight IO Libraries. Make sure you have the latest version of IO Libs as well as instrument firmware.’

Hi Brian,
Unfortunately it still isn't working. Let me give you the sequence of what I've tried. Also, I don't have any NI libs installed, brand new PC here without much else on it.
I first uninstalled the following programs:
Then Repaired Keysight IO Libraries. I then updated to the latest instrument firmware and updated the IO Libs on my instrument. I was now back up with a green checkmark on my instrument in Connection Expert. Benchvue still did the same thing, splash screen... then nothing.
I then completely uninstalled the following programs and rebooted:
And reinstalled everything. Benchvue does the same thing.
Brian,
So it turns out the NI Libs were installed, I completely missed it. They were installed under 'National Instruments Software.' I had installed an app from a vendor a few days ago that apparently relied on the NI Libs.
I went ahead and uninstalled the NI Libs, removed the Shared Components, and repaired the Keysight IO Libraries like you said.
Unfortunately, Benchvue is still doing the same thing.
@ ctw on Sep 20, 2017 6:55 AMDo you have any old Ivi drivers? Some of the old ones will break VISA. One culprit that we recently discovered is the L44xx driver:
Since BenchVue does not need Ivi drivers for most instruments, please remove all Ivi drivers. You can always re-install them if you find you need one later.
Brain
When I filter on IVI in installed programs this is what I get:
So it doesn't look like I have any of the old drivers.
@ ctw on Sep 20, 2017 7:49 AMPlease try removing the two Agilent IVI drivers and see if it helps.
Brian
Brian,
Didn't change anything.
But I did notice something new. Looks like there's been an error window stuck behind the BenchVue splash screen that didn't show up until I hovered over the BenchVue icon in the taskbar:
@ ctw on Sep 20, 2017 8:12 AMSo, dumb question. Have you tried rebooting?
Also, if this is Windows 10, there are some known issues with Windows 10 causing very long delays in program startup, after which Windows stops the services. Try going into Task Manager, services tab, and manually starting the Keysight Communications Fabric and/or Keysight BenchVue Service if they are stopped.
Brian
Yeah, definitely rebooted. I've been rebooting after every round of installing/uninstalling too.
The Keysight services are all running. I also tried restarting the Communications Fabric service, no change. I never see the Keysight Benchvue Service come up though, even after trying to launch the program:
After my last post I thought I'd try to track down where the Keysight Benchvue Service might be. Found it in C:\Program Files (x86)\Keysight\BenchVue\Platform\Service
I tried running it, and get this:
Tried something else...
I ran the exe file called "Keysight Benchvue Service Console.exe in the Service folder and got this:
Googled fips validated cryptographic algorithms... found this: Progress KB - This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms exception
Looks like it might be an issue with my IT's local security policy...
@ ctw on Sep 20, 2017 9:08 AMWell, I meant for you to go to Task Manager to try to restart services, not find the exe’s!
However, if you have FIPS enabled, that would definitely cause problems. We only recently discovered this issue, which is mostly relevant to government and military customers. FIPS is a federal security protocol. It can be turned off by flipping a bit in the registry if you want to try it.
1. Start up regedit
2. Navigate to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy
3. Set Enabled = 0
4. Reboot PC
Make sure your IT person okays this if necessary. You will also need to be an administrator to do this.

I did! Look at my post at 8:22am. I just got a little curious and wanted to try some other things.

Worked! BenchVue starts. Thanks Brian.
