Thank you Mark for your response, and your explanation.You are right, python.exe is not involved but I thought you handled the flag in your embedded calls.. When I try to start service it doesn't start and the error message is:
*Error starting service: The service did not respond to the start or control request in a timely fashion.* _svc_name_ = 'XXXXXXXXXXXXXXX' _svc_display_name_ = 'XXXXXXXXXXXXXXXXXXX' _svc_description_ = 'SXXXXXXXXXXXXXXX' _exe_name_ = sys.executable _exe_args_ = '-X utf8 "' + os.path.abspath(__file__) + '"' When I take a look to the service on Regedit I've the following situation: ImagePath = *"C:\Program Files (x86)\snapp-device-manager-win32\Python\python.exe" -X utf8 "C:\Program Files (x86)\xxxxxxxxxxxxxx\winservice_launcher32.py"* I can't find any logs about failure.... windows doesn't help me......
