Python Can'；找不到Windows注册表项，但它'；它在regedit中可见

我正在搜索特定发布者的卸载字符串，以自动卸载某些软件。我可以在regedit中看到条目。我正在搜索64位和32位注册表视图，这可以在我的代码中看到。我可以在“添加或删除程序”中查看应用程序。该软件是由环境研究系统研究所（Environmental Research Systems Institute，Inc.）发布的。我已经到处搜索了，不明白为什么我的代码找不到这把钥匙。任何帮助都将不胜感激。在函数

getUninstallers

中，在第一个try块中注释掉了一条if语句，该语句具有我试图查找的实际密钥名。在代码下面，我包含了一个regedit的屏幕截图，其中键可见

这个问题被问了无数次。搜索注册表重定向程序。在第二次打开时，您错误地使用了一个相对于“\registry\Machine”键（即HKLM）伪句柄的路径，但没有所需的

key\u WOW64\u 32KEY

或

key\u WOW64\u 64KEY

标志。它应该与父项相关，例如

subKey=winreg.OpenKey（Key，subKeyName）

。此外，请删除

bKeyName

及其所有引用。不要直接使用“Wow6432Node”键。这是API的一个实现细节，您已经在使用上面提到的标志。@eryksun感谢下面的提示和工作代码。同样，内部

OpenKey

应该使用带有相对子键路径的外部

键
句柄，例如
winreg.OpenKey（键，子键名，0，访问=（winreg.KEY_WOW64_64KEY | winreg.KEY_READ））
。请注意，标志应与按位OR组合，而不是加法。这一点非常重要，尤其是在可能已启用的变量中启用标志时（例如右：
1 | 1
。错误：
1+1
）。@eryksun编辑并测试，再次感谢您。非常感谢您的帮助！
