why install norton its rubbish? but if you must, its either a prob with your cd or the program, try right click on the cd icon and explore then find the setup exe and try that, if it fails take it back and explain to the vendor, he mite be able to tell you whats is wrong or they mite replace the disk, ps get a free anti virus like avast4 or avg both detect stuff that norton or mcafee both miss ie win32. good luck
