VerifyError: Error #1014: Class flash.ui::GameInput could not be found.

Answer:

Yeah.. I expect we're gonna get this a lot from now on.
We added flash gamepad support, which requires flash player version 11.8+. So there are two things you can do:

1. Increase the flash player version accordingly: <set name="SWF_VERSION" value="11.8" />
2. Disable gamepads on flash: <haxedef name="FLX_NO_GAMEPAD" if="flash"
   
   
   Hopefully I don't run into this problem because I will be converting my old as3 code base to haxe.
    

OpenFL is not a recognized internal or external command:

 Hmm... The lime thing worked for me. But didn't have as many sample projects as I was hoping for.
Think my next step is to download HaxeFlixel and run those sample projects and get them running on different targets.


Making blog posts of trouble shooting as I go on my journey to get Haxe and OpenFL
rolling. :)

Instead of "openfl create DisplayingABitmap", try "lime create openfl.DisplayingABitmap", and so on. We'll try and get the documentation updated.

I got this issue solved by running haxelib run openfl-tools setup
I dont remember if it is istalled by default (check by running haxelib list), if not - run haxelib install openfl-tools
