In Internet explorer click on tools>Internet Options, Under temporary internet files click SETTINGS>View Objects
A folder will open that is labeled Downloaded Program Files and you will need to find PopCapLoader Object, Shockwave ActiveX Control, and ZoneIntro Class. If you right click on each of these I am sure under PROPERTIES>dependency you will find the word "Damaged" instead of a file size. Even if you don't- delete these three things, the close everything you just opened, and shut down internet explorer, then restart your PC, then go back to internet explorer -then if you had shockwave, you need to go to shockwave dot com and download it again. As for the games, when you get to the site you'll get the pop up asking to install..
I really hope this works for you.
