Installing Avast SecureLine VPN

Running up to date Windows 8.1 as administrator and Avast VPN stopped connecting. Uninstalled the program and added in my order number and password to redownload. Clicked on install and it has been installing for over 1 hour now with no end in sight. Down load speed is 85 MBPS, do that’s not a problem. How do I get this installed back on my machine and working?
Thanks
