[Ariannamartinotti]

Hi. I'm new and I have a big problem. I downloaded maxwell and want to install it on my macbook so that I can use it with archicad.
I tried to install it but every time I throw a render on maxwell I appear a hateful writing on the pane where there should be the render...I don't know if I installed it correctly. someone can help me please I am desperate I cannot understand what my installation error is
Thank you very much
