How to set up enterprise OIDs for Windows SNMP service?

Question

I'm trying to use the SNMP service on Localhost, in Windows. I am not having a problem accessing the defined OID values of my device. I perform the operations with the sharpsnmp library.

For example, in the code below, I can change the sysContact data whose OID is "1.3.6.1.2.1.1.4":

Messenger.Set(VersionCode.V2,
                       new IPEndPoint(IPAddress.Parse("127.0.0.1"), 161),
                       new OctetString("manager"), // read-write
                       new List<Variable> { new Variable(new ObjectIdentifier("1.3.6.1.2.1.1.4.0"), new OctetString("test")) },
                       200);

But I can not integrated enterprise OID value to the system. If I run the following code, I get an error like this: "error in response. NotWritable. Index: 1. Errored Object ID: 1.3.6.1.4.1.37476.9000.128.1.1.0":

Messenger.Set(VersionCode.V2,
                           new IPEndPoint(IPAddress.Parse("127.0.0.1"), 161),
                           new OctetString("manager"),
                           new List<Variable> { new Variable(new ObjectIdentifier("1.3.6.1.4.1.37476.9000.128.1.1.0"), new OctetString("testHost")) },
                           200);

So what should I do? I could not find the necessary information on the internet. I would be very glad if you could help me.

Thanks.
