SETUP WILL NOW CLOSEAfter re-booting, log on to the internet before running IE setup.I would stick with what use have.....imhao......have you use a reg cleaner?Do you have automatic updates turned on itn WINDOWS? If so, turn that off until you get this resolved. You know the rest of the usual drill - check for adware, spyware, clean out temp files, ETC. then try again. The advice to be hooked up to the internet before starting the install itself is a good one.
