I have the following key in my registry:

under:HKEY_LOCAL_MACHINE\SOFTWARE\RSA I have value object call - WebExControlManagerPath and its value is c:\

I am trying to do this: 

var r = Registry.GetValue(@"HKEY_LOCAL_MACHINE\SOFTWARE\RSA", "WebExControlManagerPth",null);

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

But r value is always null.

enter image description here

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();
