c# - Registry.GetValue always return null

Question

I have the following key in my registry:

under:HKEY_LOCAL_MACHINESOFTWARERSA I have value object call - WebExControlManagerPath and its value is c:

I am trying to do this:

var r = Registry.GetValue(@"HKEY_LOCAL_MACHINESOFTWARERSA", "WebExControlManagerPth",null);

if(r!=null)
    ProcessAsUser.Launch(ToString());

But r value is always null.

Any ideas?

The statement of Jason is right, the operating system is the problem, the below code will help you to resolve.

RegistryKey localKey;
if(Environment.Is64BitOperatingSystem)
    localKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64);
else
    localKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32);

string value = localKey.OpenSubKey("RSA").GetValue("WebExControlManagerPth").ToString();
