When I double-click on an FTP location in Windows File Explorer that is a mapped network drive in My Computer, I'm getting an error that no such interface is supported. What should I do?
This error dates back to the early days of Windows -- probably around the time of Windows 95, once the necessary evil called the Windows registry came about. It's a problem based in how Internet Explorer (IE) handles various protocols. I've experienced this problem a few times myself. The frustrating thing is that there are just about as many solutions are there are causes.
Without knowing your specific software versions, it's hard to provide detailed advice, but here are some higher-level things you'll want to try:
- Check your computer for malware using your existing antivirus tool and then another one such as Malwarebytes, AVG or Microsoft Security Essentials.
- Remove any toolbars and related programs from IE via Manage Add-ons.
- Clear your IE browsing history and related stored data via Internet Options/General. An alternative that may work better than IE itself is CCleaner, which is very good.
- Create a new user account/profile.
- Uninstall/reinstall IE via Control Panel via Turn Windows Features On or Off.
- Upgrade to the latest version of IE (currently v11).
There are ways to re-register certain IE-related Dynamic Link Library files, but I've never had any luck with that approach to Windows File Explorer troubleshooting.
