[Xymon] Xymon Powershell Windows client

Hi,

I just downloaded the latest version of the Powershell client. I tried to install ist on a 64bit Windows 7 machine. The installation works, but I can't get the service to start. The first thing is, that powershell complains about the xymonclient.ps1 not being digitally signed. So I set the execution policy to unrestricted. When I try to start the service I get the following message:

PS C:\Program Files\xymon> .\xymonclient.ps1 start start-service : Fehler beim Starten des Diensts "XymonPSClient (XymonPSClient)". In C:\Program Files\xymon\xymonclient.ps1:2708 Zeichen:60

• if((get-service $xymonsvcname).Status -ne "Running") { 

  start-service $xymons ...

     + CategoryInfo          : OpenError: 
(System.ServiceProcess.ServiceController:ServiceController) 
[Start-Service], ServiceCommandException
     + FullyQualifiedErrorId : 
StartServiceFailed,Microsoft.PowerShell.Commands.StartServiceCommand
--------------------------------------------

When I try to start the service manually with start-service I get:

--------------------------------------------
PS C:\Program Files\xymon> Start-Service XymonPSClient
Start-Service : Fehler beim Starten des Diensts "XymonPSClient 
(XymonPSClient)".
In Zeile:1 Zeichen:1
+ Start-Service XymonPSClient

     + CategoryInfo          : OpenError: 
(System.ServiceProcess.ServiceController:ServiceController) 
[Start-Service], ServiceCommandException
     + FullyQualifiedErrorId :

--------------------------------------------

Any ideas what could be wrong?
