Don't understand this error/how to respond

[atyar]

I just downloaded,installed, and configured this on my laptop running win10(fully updated).
It generally seems to work. Yet, every time it's run, I get an error message(attached here).
Does anyone know how to correct this 'error'? Thank you kindly!
