Execute the below query and check the result. If it returns 1, then replication is installed in the server. This stored procedure is actually checking the registry and returns the result. 
DECLARE @replication_installed int;  
EXEC @replication_installed = master.sys.sp_MS_replication_installed;  
SELECT @replication_installed;

EXECUTE master.dbo.xp_instance_regread 'HKEY_LOCAL_MACHINE',   
        'SOFTWARE\Microsoft\MSSQLServer\Replication',
