I am running win xp sp3 home. This is an old Dell Dimension 5150 desktop which I am attempting to refurbish. Some have claimed my efforts are a waste of time. When trying to open a zip file, I get the "error 2815" message. This is a drivers file. Can anyone tell me what this is and how to correct it? Some websites have stated this is a registry problem. I am reluctant to screw with the registry due to info I have encountered on the Internet, ie "don't touch the registry unless absolutely necessary". Any input would be appreciated. Was unable to locate any posts regarding 2815 on this website. Grats. :)
