Unable to compile sketch

[pradeeplogu123]

I'm unable to load my custom sketch on my m5stick but when I tried with default examples it's working fine, I don't know how to resolve this…
I got this error message:

I'm got this error with win8.1 OS.

Seriously? You couldn't find a PC with Vista on it?

[pradeeplogu123]

Lol… I just downgraded my system!
