Ubuntu downloader for Windows discontinued
Due to various bugs in Wubi that have not been addressed in time for the final release, the Ubuntu team will not be releasing the Wubi installer with 13.04. You can read more about this decision here. Users who wish to try out Ubuntu without repartitioning a Windows system are encouraged to use a live system instead, booted from either a DVD or a USB disk.
