Big-IP Edge client installation fails on Windows 11

Looking at the support case logs doesn't seem to indicate any broad problems with Edge Client and Windows 11, but that error is suggestive of a Credential Guard / HVCI driver issue. You might want to try disabling that and seeing if the behavior changes.

If you don't use the built-in Edge Client firewall or DNS relay proxy, I'm fairly certain you can run the client without the F5Fltdrv.sys driver. To prepare an Edge Client package without that driver, un-check "DNS Relay Proxy" and "Traffic Control Service", then click Download.
