FileNotFoundError: Could not find a Chrome executable on this machine, please specify it yourself

Can I install Chrome on my FREE acount? I need to run this code to be able to make a screenshoot of the html file.

from html2image import Html2Image
hti = Html2Image()
hti.output_path = 'files/static/data/'
hti.screenshot(html_file=path + '/plot.html', save_as='plot.png', size=(720, 800))

But I’m getting the error that the code can’t find chome executable file:
FileNotFoundError: Could not find a Chrome executable on this machine, please specify it yourself

I saw this post with a code to install the Chrome but not sure how to do it in FREE acount
