After automatic install I get error 'platformio' could not be spawned...

System: windows 8.1 x64
Python: 3.5.1 x64
Automatic install via binary from the site.
At every launch I get red popup window with message:
'platformio' could not be spawned. Is it installed and on your path? If so please open an issue on the package spawning the process.

checked PATH, found C:\Users\user\AppData\Local\atom\bin and also C:\Program Files\Python35\Scripts;C:\Program Files\Python35\

Please uninstall Python 3. PlatformIO requires Python 2.7. See docs.

Confirmed, works after reinstall Python 2.7
However, allowing setup with incompatible environment is not an expected behavior of the automatic installer.

@orgkhnargh when 'platformio' could not be spawned., please check Python version and explain user that Python 2.7 is required

It is now not possible to install the IDE without Python 2 (as of d083f93). GUI is now more clear about the required Python version. Thanks for pointing to this!
