Sorry for being too late to reply.

You can get the result of an output parameter using WIN32OLE::ARGV.

wmi_svc = WIN32OLE.connect("winmgmts:\\\\.\\root\\cimv2:Win32_Process")
wmi_svc.invoke("Create", "notepad", nil, nil, nil)  
p WIN32OLE::ARGV # => ["notepad", -2147352572, -2147352572, 1704]

I am going to investigate why ole_method is failed.
Please wait for a while.
