Hi, I keep getting an error everytime I try to download the windows update. It will get up to like 99% and then the error would pop up. Its the Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update (KB951847) x86 and error code 57 pops up and it says that windows update has encountered an unknown error. Has anyone else had this issue? I have Windows Vista Home Premium. Thanks in advance!!
