If these buttons respond to clicking then you only need to know what the label should be and I could post some screenshots.
The buttons do respond. I was hoping I could type something on the second screen (where you locate the existing Arduino install) but it doesn't appear this is the case. I'm not sure how to progress past the second screen and I can't for the life of me figure out what's wrong with my font installs :-(
You're missing one of the system fonts that's always supposed to be part of the system. Sorry, I don't have more specific info handy.
