Windows 注册表问题

Question

我正在尝试使用 D 修改注册表中的一些值，但它一直给我以下错误：

Value cannot be set

但是，如果我用 C# 编写完全相同的代码，那么它就可以工作。是D中注册表模块的问题还是我使用方式的问题？

    writeln("Press ENTER to change language.");
    readln();
    writefln("Changing language of Sims 2 to '%s' ...", languageName);

因为您有 SOFTWARE\WOW6432Node 注册表项，所以您的系统是 64 位的。默认情况下，C# 编译器（请参阅 /platform:anycpu，它在 VS 中也默认使用）生成一个程序集，该程序集运行在 64 位系统上作为 64 位进程，在 32- 系统上作为 32 位进程位系统。

此外，默认情况下，64 位系统上的 32 位进程的注册表查询被重定向到特殊的 WOW6432Node 子项（例如，请求打开 HKLM\Software 实际上会打开 HKLM\Software\WOW6432Node，参见 MSND article "32-bit and 64-bit Application Data in the Registry"）。结果，您的 32 位 D 应用程序（就像如果运行作为 32 位进程，您的 C# 应用程序将执行的操作）实际上尝试打开 SOFTWARE\Wow6432Node\Wow6432Node\EA GAMES\The Sims 2 不存在的密钥。

要解决此问题，请在 64 位模式下编译 D 应用程序（-m64 开关）或使用 REGSAM.KEY_WOW64_64KEY 禁用默认重定向：

Registry.localMachine.getKey(keyName, REGSAM.KEY_READ | REGSAM.KEY_WOW64_64KEY);

注意：RegistryView.Registry64 可用于禁用 C# 中的默认重定向，如果它运行在 64 位系统上作为 32 位进程。
