Have a customer using IE 11 in windows 7. Every few weeks he will advise that he can no longer download files in IE. It will give him the usual message that due to security in place he cannot download files. If you go into Tools, Internet Options, Security, Internet Zone, Custom Level, then under Downloads section, File Downloads is disabled. I can temporarily resolve the issue by enabling it, however, it will switch back to "Disabled" periodically. Need help to stop this from happening permanently. This is the only pc that this is happening to in their company.
