    Hi D365FO Junior Dev,

    In addition to the replies below, you can read my blog for a possible workaround if the browser doesn't support running ClickOnce applications directly: How to open the workflow editor with the new Microsoft Edge browser - Dynamicspedia

    Hi,
     
    Addition to the below- please make sure you open workflow designer from Edge, not from Google.

    Hi,
     
    This ClickOnce error (`Deployment and application do not have matching security zones`) usually happens when you're trying to run a ClickOnce app (like `WorkflowEditorHost.application`) from a downloaded file (e.g., local disk) instead of the original trusted URL (like from D365 FO site directly).
     
    Try below steps:
    1. Do not run from Downloads folder.
       - Instead, open the workflow editor directly from within D365 FO (e.g., via Workflow Editor button in module setup).
    2. Check Internet Explorer/Edge trusted sites:
       - Add your D365 FO URL to Trusted Sites in Internet Options > Security tab.
     
    What you're using a VM or cloud-hosted D365?
     
    Thanks,
    Raj D Borad
