I'm guessing, but a few things to check.

Do you have any 3rd party anti-virus/security/firewall software installed? If so, can you disable it to see if that has any effect?

This next thing to check is to navigate to the location where NDI Tools is installed, right click on an executable and see if there is an unblock checkbox. If there is, then check this box and then see if the software will open.

Lastly, is there any entry put into the Windows Application log when you try to run an NDI tool?

Sorry for the delayed response. I have check the app and there is no option such as the one indicated above. I have disabled both AV and Firewall. I have also installed runtime tools (as OBS plugin required it)
This is the only app that does not respond to opening.
Nothing comes up in the system tray nor does anything come up in menu bar or task bar.
I’m relatively pc savvy (and I’ve even enrolled a someone who acts as a Sys admin in his company to see if I missed anything.

I don’t get any app opening no config or menu screen. Nothing. zero response.

I desperately need to use the bridge function to convert from full ndi in OBS to a compressed version to connect to my video switcher.

Please help.

Any messages in the Windows Application log?

Based on that information, I'd reinstall the .NET Desktop Runtime, current version is 8.0.27. It appears that one of the files is corrupted on that system (or at least empty).

You can get that from the Microsoft link below (second option on right column).
