I am unable to print anything using winreg module. Does it require
administrative privileges?
I am using this code sample :
import os
import errno
import winreg
proc_arch = os.environ['PROCESSOR_ARCHITECTURE'].lower()
try:
proc_arch64 = os.environ['PROCESSOR_ARCHITEW6432'].lower()
except KeyError:
proc_arch64 = None
pass
if proc_arch == 'x86' and not proc_arch64:
arch_keys = {0}
elif proc_arch == 'x86' or proc_arch == 'amd64':
arch_keys = {winreg.KEY_WOW64_32KEY, winreg.KEY_WOW64_64KEY}
else:
raise Exception("Unhandled arch {}".format(proc_arch))
for arch_key in arch_keys:
key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, r"SOFTWARE\Python", 0,
winreg.KEY_READ | arch_key)
for i in range(0, winreg.QueryInfoKey(key)[0]):
skey_name = winreg.EnumKey(key, i)
skey = winreg.OpenKey(key, skey_name)
try:
print(winreg.QueryValueEx(skey, 'DisplayName')[0])
except OSError as e:
if e.errno == errno.ENOENT:
pass
finally:
skey.Close()
