Hello all,
I had the same issue with attempting to update the iOS 5 software for the past week now and receiving the same failed update (with error message). The anti-virus program that I use is Kaspersky Pure. I googled and read all threads on how to fix this issue. Most people recommended doing a direct download, which I initiated, but that didn't work or uninstalling the anti-virus software, which I can't do because I don't have my installation cd. So, what I did was the following, I wasn't expecting for it to work but I guess anything would help at this point; however this technique worked perfectly and now I have the update 🙂! Keep in mind I have Windows Vista.
1. I went to Windows Firewall with Advanced Security
- A pop up window will display and you have to go to "Windows Firewall Properties"
- Under (all 3 ) Domain Profile, Private Profile, and Public Profile set the "Firewall State" to off. Hit Apply then exit.
2. Next I went to Kaspersky Pure and did the following:
3. Vioila! The update worked.
Hope this helps you guys.
