I'm trying to install IE 10 or IE 11 in Windows 7, using Windows Update, but it always fails with an 8024AFFF error. Searching the web, I found many people with the same problem with all sorts of possible fixes, but none of them worked.
All the other updates I tried work fine, just the IE 10 and IE 11 updates are failing. I have enough disk space, a good internet connection, and Windows has very little installed software and it is just common software. Several antivirus scans didn't find any virus or spyware.
So what is
error 8024AFFF and how do I fix it?
