Here is what I do step by step to set it up. If you did anything different or the exact same let me know.
Step 0) Remove any existing installations of xampp (make sure its not installed as a service and not running, suggest rebooting the computer to make sure)
Step 1) Download xampp from http://sourceforge.net/projects/xampp/f ... e/download
Step 2) Click "Yes" or "Continue" on each screen. Let it install to C:\xampp (it will ask you if you want to run Step 3 "click yes")
Step 3) Navigate to C:\xampp and find xampp-control.exe Application
Step 4) Start MySQL and Apache (make sure they both turn green) IF THEY DON'T: (most likely apache) check this link: viewtopic.php?f=16&t=69784#p239058
Step 5) Assuming both MySQL and Apache go green go to your browser and type in the address bar: http://localhost
Step 6) You should now see a screen saying XAMPP in your browser
