Problems Using Open Office

[Hayley Nelson]

Hello
I have a google pixelbook and am having issues using Open Office.  Once
downloaded I try to open it and it opens it via Painter???  and It won't
let me open it up any other way.  I've only had the computer for a few
months so I'm not a pro at it.   If you have any suggestions on how to help
me please let me know.
Thank you
Hayley Nelson
