Hi Cristián,

I looked at the issue you mentioned but the problem I have doesn't get 
anywhere near that far!

When I use PyInstaller and run the .exe I get:
'Fatal error detected' 'Failed to execute script 

And when I use cx-freeze and run the .exe I get:
'application failed to start because no qt platform plugin could be 
This is despite having a plugins folder with plugins/platforms etc.

So I still can't create a deployable package.
