Hello,

the installation of bounjour service fails due to an oversight in
CreateServiceA/W().
The installer writes registry keys at some point, like:

"SYSTEM\\CurrentControlSet\\Services\\Bonjour Service\\Parameters"

and later does explicit installation/creation of service using
CreateServiceA/W() API call:

offending code:

--- snip dlls/advapi32/service.c ---
SC_HANDLE WINAPI
CreateServiceW( SC_HANDLE hSCManager, LPCWSTR lpServiceName,
                  LPCWSTR lpDisplayName, DWORD dwDesiredAccess,
                  DWORD dwServiceType, DWORD dwStartType,
                  DWORD dwErrorControl, LPCWSTR lpBinaryPathName,
                  LPCWSTR lpLoadOrderGroup, LPDWORD lpdwTagId,
                  LPCWSTR lpDependencies, LPCWSTR lpServiceStartName,
                  LPCWSTR lpPassword )
{ 
...
    /* Loop through the registry to check if the service already exists and to
     * check if we can use the given displayname.
     * FIXME: Should we use EnumServicesStatusEx?
     */
    len = sizeof(buffer);
    while (RegEnumKeyExW(hscm->hkey, index, buffer, &len, NULL, NULL, NULL,
NULL) == ERROR_SUCCESS)
    {
        HKEY service_key;

        /* The service already exists, so bail out */
        if(!lstrcmpiW(lpServiceName, buffer))
        {
            SetLastError(ERROR_SERVICE_EXISTS);
            return NULL;
        }  
 ...
}
--- snip dlls/advapi32/service.c ---

The service does not really exist prior the call because only the "Parameters"
subkey was written by installer.
The function makes incorrect assumption if the service name subkey exists under
"SYSTEM\\CurrentControlSet\\Services" all other service config data exists too
and returns with ERROR_SERVICE_EXISTS without updating the data. 

The code following the call assumes "ok" and tries to start the service.
Due to missing service data (like binary path) it fails.

Solution: overwrite/update service registry data even if some partial data
exist.

Regards
