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’.
Wrap all of the string in parentheses:
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.
