I downloaded XCode 4.2 from apple developer website. after I download it and try to install, error message pops out saying "The Following Disk Image Couldn't be Opened , xcode_4.2_and_ios_5_ not recognized " has anyone here experienced this kind of error?
Mac Os X 10.6.8
Thank you guys!

Sounds like a corrupted disk image... may just have been a bad download. Restart your computer, and if you still have the same problem, re-download. (And obviously make sure you're downloading the Snow Leopard version of Xcode since you're running it on 10.6.8... but I'm sure you were, and that wouldn't in any case lead to the error you described.)
