I've been trying to download the latest release from the website, but even though I'm selecting 13.04 64-bit as my option, the download begins for 12.04.2 32-bit. Any ideas as why this is happening? I'm downloading on Windows 8 in Dell Inspiron.
Just to make it easier on you, to download Ubuntu 13.04 64bit just click Here, and that will download the right file.
When browsing to "Get Ubuntu now-> Ubuntu Desktop" on the main page for Ubuntu you will be directed to a donation page. After having entered your choice you should be directed to the download page for Ubuntu
On this page you will have a choice for downloading Ubuntu 12.04 LTS, or further down on this page for Ubuntu 13.04, each having a dropbox to choose 32-bit (default), or 64-bit architecture:
If you do not see this page there may have been an error.
In this case, or to choose another download mirror or a BitTorrent download we will also have access to downloads from the following page:
Of course you will see download from various other non-official sources. This may work fine, but keep in mind to be carfeul to not download a customized version different to the official release.
