It may be an error on my end but it looks like it could also be your browser settings. Perhaps try the windows exe?
I wish. i dondt see a windows exe version
Look under the download section, you should see DergieClicker.Win1.1.zip
well it because i am using the app. and this is all i can find. maybe put the windows version in the install button next time?
It's also possible that the version of Windows is too low
