Hi All,

I have 2 code , one a compile.exe and two is Wacther.exe.
In compile.exe can use "process.start" and twin "Add/Remove" for using HKey....
In Watcher.exe a code use filesystemwatcher.
My problem is, it can start a Watcher.exe but at the windows Load become error "The program Stop Working".

somebody can give a real code.

here a code;
