System.ComponentModel.Win32Exception: Path not found

Question

In my WPF Application i can use this command:

Process.Start(@"C:\Windows\System32\appwiz.cpl");

But this is not working:

Process.Start(@"C:\Windows\System32\firewall.cpl");

i got (in german): System.ComponentModel.Win32Exception: "Das System kann die angegebene Datei nicht finden". File not found. But when i put C:\Windows\System32\firewall.cpl to my file Explorer, Firewall.cpl is opening. I tryed some others:

OK:

• desk.cpl
• hdwwiz.cpl
• inetcpl.cpl
• intl.cpl
• joy.cpl
• main.cpl
• mmsys.cpl

NOK:

• Firewall.cpl
• igfxCPL.cpl
• compmgmtlauncher.exe

What ist the Problem?

Answer 1

According to the comments,the solution is c:\windows\sysnative\firewall.cpl or Project > Properties > Build tab , "Prefer 32-bit" unticked.
