I had the same problem on two different computers (XP and Win 7 32 bit) with different error numbers.
In my Windows XP, the problem arose because of something else listening on port 80 . On my Win 7, I renamed the folder to another and ran setup_xampp.bat and solved it.
Renaming the folder back to its original name (C: \ XAMPP) and starting the installation caused the problem, so I left it with C: \ XAMPP2.
