It seems that ever since IE9 there has been a weird bug with Internet Explorer and redirected folders, specifically when you are trying to download a file. Sometimes the file will download, other times, and it’s very random, it will not work. The usual error is: This program couldn’t be downloaded in the download manager.
It appears to happen to anyone who has redirected folders enabled – this is going to be more for folks who are in the corporate world or someone tinkering with their own Active Directory setup at home.
It also appears that Microsoft fixed this in IE9 and released a patch but IE10 seems to have broken it yet again and there is no word from Microsoft on whether or not this will ever be fixed.
If anyone knows anything or maybe even an IE dev will see this but we’d like an answer please!
