How to validate the existence of a registry path?

Question

I was wondering how can I validate the existence of a registry path?

This is the code I am using and I would like to know how I can validate the existence of PATH?

string PATH = @"SOFTWARE\GT37\0010\";
        RegistryKey registryKey = Registry.CurrentUser.OpenSubKey(PATH);

Your code contains a lot of stuff that is totally, totally irrelevant to your question. You need to keep it minimal so we can provide better and faster answers. Please see [ask]. — Peter B, Aug 02 '17 at 14:06

From description you provided it seems you want to verify that registry key

HKCU\SOFTWARE\GT37\0010\

exists ?

Please note that User-specific settings will be written to HKCU\Software and machine-specific settings to HKLM\Software. Based on your scenario you might want to check both.
Anyhow, in order to check whether a key exists or not you just try to get it's value like this

var key = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\GT37\0010");
// if you want to check under HKLM
//var key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\GT37\0010");
if (key == null)
{
    // Key does not exist
}
else
{
    // Key exists proceed with your logic
}
