I have a computer with Windows XP. Is there a way I can retrieve saved files from the hard drive on a system that explorer will not start on because of missing dll files? Or is there a way to reinstall the missing dll files using only "Task Manager" in the "Safe Mode"? What I believe got me to this point was the Windows help website. Following their directions for correctly installing Microsoft.Net Framework 1.1 service pack I had to remove a bunch of files and reinstall it. Upon re-installation got a pop up that said the service pack did not properly install. Not thinking about that I rebooted the system. Now i get messages that explorer does not start because iertutil.dll is missing. I think this is the first hurdle in a bunch of that are missing. I have been to the Sony website to download on a thumb drive to grab the Sony Utilities DLL update, Version 6.4.0.06290, Dated 7/17/2006 believing that if I can get this onto my Sony VAIO it will fix the problem. Is there anyone who can provide guidance?:(
