My processor is 64-bit - does that mean I need the amd64 image?

I tried installing Ubuntu 32-bit on my computer, but before the installation had really started, I got the error-page ending with panic occured, switching back to text console. I then tried installing the 64-bit version, and the installation started without problems.

Is there a fix to this problem, or do I need to use the 64-bit version? Will there be problems finding 64-bit versions of programs etc?

@Alvar yes ur rite , but it also depend on situation & also on weather condition –  One Zero Feb 12 '12 at 19:34
    
It could have been that the 32-bit ISO you downloaded got corrupted. –  devius Feb 12 '12 at 19:50
    
It sounds like you've burned a bad CD. 32-bit should work on 64-bit machines. You can use the Check disc for errors option in the boot menu of the Live CD to be sure. –  Lekensteyn Feb 12 '12 at 20:05

64-bit Ubuntu is very very well supported, and at this point you will likely have more difficulty finding 32-bit versions of your applications than 64. 64-bit is almost always the recommended choice.

To anwser your question though, technically 32 bit should have still worked.

No you don't have to.

But some operations in the CPU will go faster with a 64-bit operating system. it's an option you have either 32-bit or 64-bit. The 32-bit will work just as good as the 64-bit will.

It's a free choice, enjoy it! :)
