Is there any simple way to block internet for only specific app?

What I have tried:

I managed to do it only for whole internet, but don't know how to do it for only one specific app - disable internet access for it and enable back on after a while.

there is no really generic solution - it may be possible, but it depends on your firewall.

That wouldn't work on win 7, also I need to block specific window/process, not whole .exe (because that app is running more than once and I need to block only one of them).

Then you probably can't do it at all.

You can't do that. You can either block for every instance of an .EXE or you can't block it at all.
