我正在创建一个python脚本，用于在注册表中的Uninstall文件夹中查找已安装的程序，该脚本在32位计算机上运行良好，但在64位计算机上出现wmi错误。 我无法在64位计算机上获得用于python的wmi模块。那里有一个吗？ 请忽略缩进错误。 我在某个论坛中发现了这个脚本，对于没有给予相应作者的应有的信任而道歉
r = wmi.Registry()
result, names = r.EnumKey (hDefKey=HKEY_LOCAL_MACHINE, sSubKeyName=r"Software\Microsoft\Windows\CurrentVersion\Uninstall")
separator = "*" * 80
keyPath = r"Software\Microsoft\Windows\CurrentVersion\Uninstall"
for subkey in names:
try:
path = keyPath + "\\" + subkey
key = OpenKey(HKEY_LOCAL_MACHINE, path, 0, KEY_ALL_ACCESS)
try:
temp = QueryValueEx(key, 'DisplayName')
temp1 = QueryValueEx(key, 'DisplayVersion')
temp2 = QueryValueEx(key, 'Publisher')
display = str(temp[0])
display_ver=str(temp1[0])
display_p=str(temp2[0])
print ('Display Name: ' + display + '\nDisplay version: ' + display_ver + '\nVendor/Publisher: ' + display_p +'\nRegkey: ' + subkey + '\n')
except:
print ('Regkey: ' + subkey + '\n')
except:
fp = StringIO.StringIO()
traceback.print_exc(file=fp)
errorMessage = fp.getvalue()
#error = 'Error for ' + key + '. Message follows:\n' + errorMessage
#HelperFuncs.LogError(error)
答案 0 :(得分：0)
尝试使用_winreg而不是wmi，我相信64位的注册表树略有不同，使32位和64位应用程序分开，因此您可能需要枚举2个注册表树。
答案 1 :(得分：0)
这可能不是使用this实现的最佳代码，但它适用于我的应用程序。我希望你能用它或改进它。

结果确保始终显示名称。考虑到我是Python新手，解决这个问题非常困难。但无论如何，如果某个应用程序在“值”列表中没有“显示名称”，它会使用显示名称的最后一个键地址。
