HI my search on my Windows Xp has worked great for forever until a few days ago, now it says that I don't have the necessary files or something and I need to run setup. I click on run and type in setup and it comes up with this message "Please go to the Control Panel to install and configure system components" I click on Control Panel and from there it either freezes or I click on everything trying to figure out what its talking about. I'm seriously stuck and I really am worried. Also since this, my itunes will not open, I've uninstalled it and re-downloaded it and everything. Any help will be greatly appreciated. Thank you, Chelsea.
