About Windows PS Client

[dOCtoR MADneSs]

Hi,

I found this Xymon client :
http://xymon.svn.sourceforge.net/viewvc/xymon/sandbox/WinPSClient/
I tried to install it the way I found logical.

1st : I fought with Windows 7 Home Premium to allow execution on
PowerShell scripts. I finally edited registry and allow it manually.
2nd : As administrator, I ran "powershell", then tried to install the
service this way :
.\xymonclient.ps1 install

But I got many errors about adding service and modifying registry (all
errors are related to permission denial).

Can D Baldwin, or anyone else informed about powershell and Xymon client
installation, help me ?
