IE 8 on Win XP SP3 briefly opens then immediately closes when starting Windows normally and in Diagnostic Startup. However, IE 8 opens and works fine in Safe Mode With Networking. I tried resetting IE but that didn't help. I also cannot run Windows Update. I tried Solution 3 from here but it didn't help: http://cnedelcu.blogspot.com/2012/05/top-3-fixes-for-internet-explorer-wont.html It appears that you can no longer download IE 8 for Win XP from Microsoft so I haven't been able to try uninstall/reinstall. MBAM didn't find any malware. I also tried the Microsoft IE FixIt but that didn't help. Please help. Thank you.
