I had the same problem and wmi module author (Tim Golden) gave me the
solution which;


import pythoncom

# call this function after the run function definition
pythoncom.CoInitialize()


So your function becomes;

 def run(*args):
        pythoncom.CoInitialize()
        c = wmi.WMI ()
        memory=c.Win32_LogicalMemoryConfiguration()[0]
        info='Total Virtual Memory: '\
                +str(int(memory.TotalVirtualMemory)/1024)\
                +'MB'
        print info
