Error running hello world on Win7-x64

[moonghg]

1. on Win7-x64, installed Rust by 1.0.0-alpha 64-bit installer(included path environment).
2. In CMD run "rustc" compile successful, created a new file: main.exe.
3. Run main.exe, report an error that has stopped working.

I think more information is necessary.

• Open CMD and run echo %PATH%, what does it output?
• What anti-virus are you running? (Possibly what's causing it.)
• Are you running from CMD or double-clicking the .exe?
