Update

Installing Windows 11 24H2 Preview Patch KB5058499 introduces a breaking change in the digital signature Win32 API call WinVerifyTrust, which prevents Ivanti agents, including agents for Security Controls, Ivanti Neurons, and Patch SDK, from functioning.

Workaround:

Uninstalling KB5058499 and restarting the system will enable existing agents to function again and new agents to be installed.

Additionally, a new Ivanti Neurons agent will be pushed later today to mitigate this issue permanently.
