What happens if you try downloading in Internet Explorer?

Type: iexplore.exe

Hit Enter

Try downloading again.

If that does not work, open Windows Defender Security Center

Open App & browser control

Toggle off 'Check apps and files', SmartScreen for Microsoft Edge'

I'm Greg, a volunteer installation specialist and 8 year Windows MVP, here to help you.

If you had MacAfee on that PC then it is probably the cause since it's the worst thing you can install to Windows and will often ruin the install beyond repair.

Please go to Settings>System>About to see what Edition of Windows 10 is installed? Windows Defender Application Control is used to restrict install of any applications that don't come from the Microsoft Store app. It is possible you have this edition of Windows and need to use the free Upgrade to Windows 10 Pro before it expires in March. See: https://www.cnet.com/news/how-to-switch-from-wi...

If not what I would do if you haven't yet is manually install Fall Creator Version 1709 by installing Media Creation Tool and choosing to Upgrade Now. http://windows.microsoft.com/en-us/windows-10/m....

This the most stable method to upgrade to the new version (which you need anyway) and will bring you fully up to date with reinstalled Windows that often will solve any other problems you have - like with buggy Windows Updates which are the last place I'd get the new version from.

You can use the same tool to download the ISO or create bootable media so you only need to do it once, and have the bootable media for repairs or possible Clean Install.

If there are any hurdles during the Upgrade see these steps to optimize the install as this is evidence it's corrupted: http://answers.microsoft.com/en-us/windows/wiki...

You can also go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

But remember that a factory or Upgrade install are inferior installs that most enthusiasts would never run in the first place because they'd expect endless issues. Most prefer to do the gold standard Clean install from this link which has had no reported issues: http://answers.microsoft.com/en-us/windows/wiki...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I'll keep working with you until this is resolved.

Give this a try next.

Open Windows Defender Security Center

Click Virus & threat protection

Click Virus & threat protection settings

Toggled off Controlled folder access

May ask which Antivirus utility you are downloading? WDSC might be protecting you for a good reason.

I tried both of those options and neither worked again. It brought up the same error message as before with both of those new options.

I'm attempting to download McAfee, I previously had it downloaded on this computer but I recently reset my computer and I wanted to re-download it. Also that last attempt still failed.
