how to check which systems runs x64 or x32

[pschulz]

This is my processor = AMD Athlon II , I considire it as AMD64, am I wrong?
have installed Win10 on my lap, have excpect Is64bit givs me a 'true', but it doesnt.

I ask, cause this is the way I like to proof, f it has 64bit or 32bit system.

bool Is64bit = string.IsNullOrEmpty(Environment.GetEnvironmentVariable("PROCESSOR_ARCHITEW6432"));

to come finally to this point

 if (Is64bit)
                {
                    searcher = new ManagementObjectSearcher("select * from Win64_Processor");
                    foreach (ManagementObject share in searcher.Get())
                    {
                        // first of all, the processorid
                        strProcId += share.GetPropertyValue("ProcessorId").ToString();
                    }
                }
