Had the same issue
it actually does download and saves a chrome extension file - just change the file extension back to .zip - and alls good
just wanted to let you know that chrome doesn't let me download your new wallet because of malware suspicion.
Hello,
Let me know if more people have this problem!
In Chrome you can go to settings --> Advanced --> Protection phishing / malware then uncheck the box for the download
