WindowsError: [Error 740] The requested operation

问题:

I have disabled UAC and running my script in python.

command = "abcd.exe"
subprocess.Popen(command,stdout=subprocess.PIPE,stderr=subprocess.PIPE).communicate()

Also, I set the application abcd.exe from its property to run as admin.

Then I'm getting the following error:

WindowsError: [Error 740] The requested operation requires elevation

回答1:

You could try using:

subprocess.call(["abcd.exe"], shell=True)

Basically the important part here is shell=True; if set to False, then you will get the following error.

WindowsError: [Error 740]

回答2:

I believe that the problem is with using subprocess.Popen.

I also think that your question has already been answered here: Request UAC elevation from within a Python script?
