ora-12560 “TNS Protocol Adapter Error” when installing database

Have you find this error, there are many cause of this error, but if this is happened when installing database then this is probably because either the service is stopped or because you connected to computer remotely using remote desktop connection.
so to install it you must make sure that the tns listener service is up and you are connected not through RDP, because you can connect it virtually or using another remote application like teamviewer or vnc variants.
remember this is only when you are installing database, if this error occurs in another kind of activity then the solution might be different.
