Install Windows service on a remote machine using PowerShell 2.0

Question

I want to use PowerShell 2.0 to install a Windows service after detecting if the service exists. I have the part to detect the service working but can't get the install to work.

$mc = [wmiclass]"\\"+"$ServiceServer\ROOT\CIMV2:Win32_Service"

Running this line produces this error:

Method invocation failed because [System.Management.ManagementClass] doesn't contain a method named 'op_Addition'.

If I just hardcode the server name it seems to work. Any idea why? — Kenoyer130, Jan 11 '11 at 20:54

Wrap all of the string in parentheses:

$mc = [wmiclass]("\\"+"$ServiceServer\ROOT\CIMV2:Win32_Service")

The problem is that [wmiclass] is casting just the first string "\\" to [System.Management.ManagementClass] which then is trying to add itself to a string.
