尝试修改服务 {serv_name} 的 DisplayName 信息为 {serv_displayname}，但该服务

Error message

尝试修改服务 {serv_name} 的 DisplayName 信息为 {serv_displayname}，但该服务未安装！

What it means

Thrown in Com_ServiceOS.Config.Modify.DisplayName's else-branch when Query.IsCreated(serv_name) is false at entry (Com_ServiceOS.cs:436-439), guarding against editing a non-existent service. The throw is caught by DisplayName's own catch and it returns false (Com_ServiceOS.cs:441-445).

Solutions

1. Pre-check Query.IsCreated and Create the service first if absent.
2. Verify the ServiceName with `sc query`.
3. Treat false as 'service not present; nothing to change'.
4. Order Create before Modify.

Example fix

// before
Com_ServiceOS.Config.Modify.DisplayName(name, display);

// after
if (Com_ServiceOS.Query.IsCreated(name))
    Com_ServiceOS.Config.Modify.DisplayName(name, display);

if (Com_ServiceOS.Query.IsCreated(serv_name))
    Com_ServiceOS.Config.Modify.DisplayName(serv_name, serv_displayname);
// else: nothing to reconfigure

static bool ServiceRegistered(string name) => Com_ServiceOS.Query.IsCreated(name);

When it happens

Trigger: Calling Modify.DisplayName for an unregistered, already-deleted, or misspelled service, or when GetServices throws so IsCreated returns false.

Common situations: Configuration step before install; name drift after a rename; using DisplayName where ServiceName was required.
