Service stops after a few seconds with error 1053

Hello,

I have successfully installed my script as a service using the following:

Run(@ScriptDir & "\instsrv.exe " & $szServiceName & " " & $szFileName, @ScriptDir, @SW_HIDE)
   ;RegWrite("HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\" & $szServiceName, "Type", "REG_DWORD", 272)
   RegWrite("HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\" & $szServiceName, "Type", "REG_DWORD", 0x110)
   RegWrite("HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\" & $szServiceName, "Start", "REG_DWORD", 2)
   RegWrite("HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\" & $szServiceName, "DisplayName", "REG_SZ", $szServiceName)
   RegWrite("HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\" & $szServiceName, "ObjectName", "REG_SZ", "LocalSystem")
   RegWrite("HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\" & $szServiceName, "Description", "REG_SZ", $szDesc)
   RegWrite("HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\" & $szServiceName & "\Parameters", "Application", "REG_SZ", $szFileName)

When I now start the service it stops after a few seconds with error 1053. I can see that the script is running until it reaches the following loop:

$VergangeneZeit = TimerDiff($TimerStart) / 1000
Do
  Sleep(1000)
Until ProcessExists("WKix32.EXE") > 0 or (TimerDiff($TimerStart) / 1000) - $VergangeneZeit > 900

I assume that Windows expects some interaction with the script but I do not really know what to do at this point. Has someone maybe a hint for me?

Many thanks in advance,

best regards
