using RegCreateKeyEx gives error code 5
提问by surendran
I used RegCreateKeyEx from a win32 application(VisualStudio 2008) in 64 bit windows(Project built with target x64). It was able to create a registry entry. Now I have a dll file (Project built with target x64) which too wanna create registry entry but my dll is returning error code 5(Yeah! its a sign of access denied). My samDesiredflag have KEY_ALL_Access+ In linker->manifestfile->run as administrator chosen which still fails with error code 5. Whereas it works perfectly in 32bit windows(Project built with target x86). Am i missing something? NOTE:I'm trying to create an entry at HKEY_LOCAL_MACHINE.
我在 64 位窗口（使用目标 x64 构建的项目）中使用了来自 win32 应用程序（VisualStudio 2008）的 RegCreateKeyEx。它能够创建一个注册表项。现在我有一个 dll 文件（使用目标 x64 构建的项目），它也想创建注册表项，但我的 dll 返回错误代码 5（是的！这是访问被拒绝的标志）。我的samDesired标志有KEY_ALL_Access+ In linker->manifestfile->run as administrator selected，但仍然失败并显示错误代码 5。而它在 32 位 Windows（使用目标 x86 构建的项目）中完美运行。我错过了什么吗？ 注意：我正在尝试在 HKEY_LOCAL_MACHINE 创建一个条目。

You can't create a registry key in HKEY_LOCAL_MACHINEbecause this isn't a hive. You need to put your key in HKEY_LOCAL_MACHINE\Softwareor (less probably) one of the other hives.
您无法在其中创建注册表项，HKEY_LOCAL_MACHINE因为这不是配置单元。您需要将钥匙放入HKEY_LOCAL_MACHINE\Software或（不太可能）其他蜂箱之一。
I don't know why this appeared to work when you were running 32-bit code in WOW64, perhaps this is a side-effect of the way the 32-bit view of the registry is presented.
我不知道为什么当您在 WOW64 中运行 32 位代码时这似乎有效，也许这是注册表的 32 位视图呈现方式的副作用。
