String is returning as String.String[] instead of value from registry

Can anyone shed some light on this?

I am querying the registry for a key value, on some image version it returns the value, and others it returns String.String[] instead.

What does that mean? How can I force it to read the key right (I have verified there is text there on the machines it returns wrong).

static string callImageVs(string PCName)
        {
            string imageVs = null;

            RegistryKey regKey = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, PCName);
            regKey = regKey.OpenSubKey(@"SYSTEM\Setup\");

            imageVs = Convert.ToString(regKey.GetValue("OEMDuplicatorString"));
           
            regKey.Close();
            

            return imageVs;
        }

What is the registry type of the key you are querying? REG_MULTI_SZ, REG_EXPAND_SZ, REG_SZ, etc.?

OK, so if I would have though about this yesterday I probably could have landed the issue.

The problem is that we are moving from Ghost to SCCM / OSD.

OSD writes a String to the OEMDuplicatorString, Norton writes a Multistring.

So I had to do this:
string imageVs = null;

            RegistryKey regKey = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, PCName);
            regKey = regKey.OpenSubKey(@"SYSTEM\Setup\");
            string OEM = Convert.ToString(regKey.GetValueKind("OEMDuplicatorString"));
            

            if (OEM == "MultiString")
            {
                string[] temp = (string[])regKey.GetValue("OEMDuplicatorString");
                for (int i = 0; i < temp.Length; i++)
                {
                    if (temp[i] == null || temp[i] == "")
                    {
                        //nothing
                    }
                    else
                    {
                        imageVs = temp[i];
                    }
                }
            }
            else if (OEM == "String")
            {
                imageVs = Convert.ToString(regKey.GetValue("OEMDuplicatorString"));
            }

            regKey.Close();
            

            return imageVs;
