Labview NXG 5.1 stuck in splash screen

[Schnappi01]

Hi,

I just installed LabVIEW NXG 5.1 on a clean new PC and it doesnt start. If i start it without administrator rights it wont even start and i if i start it with the administrator rights it gets stuck after "Loaded SharpDX.DXGI".

I also installed LabVIEW 2020 SP1 without any problems and everything works.

I have tried to reinstall it many times, I also clear all old nxg folders and the catch. I tried to "repair" it with the NI Package Manager. But nothing I tried worked.

Has someone an idea how i can fix that?

Thanks for your time 🙂

The best advice I can give you is to do a Google search for NXG and splash screen and then look up the links that lead you to this forum.  This search method yields much better results than if you tried using the forum search function.  I know you already did a seacrh, but hopefully this helps you.

I don't know too much about NXG, except it can sometimes take minutes to load.

SharpDX is a .NET wrapper around DirectX, so you might try installing additional DirectX components in case that's the reason it is failing to load: https://www.microsoft.com/en-us/download/details.aspx?id=35

You can see additional startup info from NXG by using an ETW Viewer. Grab the ETW Viewer attachment from this post, then run it before running NXG. After the splash screen freezes, click the Save button in the lower left to save the current session log and then post it here.

In case you were unaware, LabVIEW NXG is no longer being developed by NI - version 5.1 is the last release. I wouldn't sweat it too much if you can't get it running.

Thanks for your help. I installed the additional DiretX components but that didnt help, i guess because the splash screen said "loaded ..." so that its stuck loading the next one.

I also used the ETW Viewer and will attach the log to this comment.

Are they really dropping LabView NXG? why? isnt that the new thing?

Again thanks for your time 🙂

It was set to replace LabVIEW, but I think NI underestimated the Herculean task of rewriting it from scratch, and it's since been shelved.

Thanks for getting that log. I had a look through it and saw one error toward the end, with the message "Discovery back-end refresh timed out." 

What's causing the timeout is unclear though, but from the logs it looks like NXG has DMM, FGEN, FlexRIO, DAQmx and a lot of other addons installed. I'd probably try uninstall NXG and all of it's addons, and then reinstall just vanilla NXG and see if that launches. Then if you need any addons, install them individually through NIPM.

Hi, did You manage to solve the problem? I had to reinstall the NXG, and it stops on the splash screen with "loaded package management". I reinstalled it multiple times, used the repair tool etc. Nothing works 

Thanks
