ok,
It's this line who crash the service :
self.WMIService
=win32com.client.GetObject(r"winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
why this function goes when it is not a service?
with IDLE -> ok
with py2exe executable (no windows service) -> ok
with py2exe service option true (windows service) -> CRASH....
