Win11 24H2 client 406 error

Windows client v3 stopped working, I assume after a Win11 update.

Same error as in this post “Xibo v3 support for Windows 11

There didn’t seem to be a resolution there.

I upgraded the client to the current version 406. Getting a similar error as follows:

Anything I should try?

Thanks

This happens on systems with tightened code-integrity policies (Windows 11 Smart App Control, WDAC, AppLocker, some AV products). You could try to add a white list or turn off that feature if you can work out which of them is causing it.

I’ve reported a bug for it here to see if we can improve it how its handled:

There is a beta release available for you to try: https://xibo-firmware.fra1.cdn.digitaloceanspaces.com/Windows-Test-MSI/xibo-client-v4-R407.1-win32-x86.msi

It prebuilds the DLL that is being blocked by windows and ships it in the MSI as a signed DLL.

Full disclaimer, I am not sure if it will work as I wasn’t able to reproduce the issue locally, so it is a theoretical fix.

Please let me know if it solves the issue for you.
