I have Windows XP in my pc and just few days back, it is prompting me to select which appplication to use when opening any software? If I am trying to update using Windows Update, then it will ask me to download and then a box appears asking to save, which I do, and then the Windows ask me which app to use that pops up again? I am also getting a message "windows/system32/rundll32.exe application not found." Any ideas?
