I have twice tried to download the 64 bit version of Ubuntu 13.04 (from the official site) and each time I have checked it after the install it has been the 32 bit variety. I could understand this if I was running 32 bit architecture but I have an AMD 64 processor. Any suggestions would be welcome, probably!

How do you check if it's 32 or 64 bit after install? –  Nullet Sep 18 '13 at 20:13
What is the output of uname -a ? –  Arnold Sep 18 '13 at 20:23
Your download should be called ubuntu-13.04-desktop-amd64.iso what is the name of the ISO you downloaded –  damien Sep 18 '13 at 22:16
