It's likely a bad burn on the CD - based on historical reporting of errno
22. Try booting your computer from that CD and run the CD check from the
extended menu (hit space when you see the keyboard/man icon). That should
confirm it.
You can either run wubi.exe standalone (as suggested) or with the
downloaded ISO in the same directory - but whichever way make sure the bad
cd is not in the drive or wubi will find it and fail again.
