LabVIEW application 2020 on windows 11 32 bit

[LVNinja]

I developed an application on LV 2020 32 Bit. When I tried to run on Windows 11 it showed the message bellow. I configured the windows to run 32 bit applications. 

It uses Active X to call a third application from Keyence. It runs on Windows 10 without any issues. 

What is the best way to get NI to help with support ?

I have a sad feeling we are all going to be referring to this shortly, if we haven't already ...

NI Product Compatibility with Windows 11 .

Do you know for sure that the Keyence application and its ActiveX interface work with Windows 11?

It's easy to try and blame NI for this, but on Windows edition changes most of the time when something goes wrong (especially with the 0xC0000005 "access violation" error), it's because whoever made some binary that you're interacting with (ActiveX, DLL, device driver, etc.) has not updated it for Windows 11 yet.

You can try downloading LabVIEW 2022 or later (2022 being the first to officially support Windows 11), and rebuilding your application.  Use the 7-day free trial if you don't have a license for any newer version yet.

However, apart from that you pretty much have to go through Keyence.  As soon as you bring 3rd party binaries into the picture, the amount of support NI can provide is quite minimal.

Thank you all for your messages.

Update: I ran the same application on a machine that was upgraded from windows 10 to windows 11 and it all works. It was previously installed when still running Win 10. 

I faced the issue when I did a fresh install on a  Win 11 machine that didn't had it installed. 

I created a small exe calling a simple function on Active X and it runs well on the win 11 machine. I must say that my application uses database kit as well. Still troubleshooting. ...
