Help! After I downloaded Ubuntu 12.04 and 13.04 Desktop version, I find that I can't install it, as it doesn't work! It says that its not a valid win32 application and I know it's not.

But why is it that, if I use my very old first version of Ubuntu Linux desktop that was delivered to me from Ubuntu - it can still install normally even though it has no updates.

How come this version that I download from your link on the Ubuntu website, is not working? The folder size is 0kb.

I really wanted to have the 12.04 version of Ubuntu Desktop... I really want to install Ubuntu inside my Win Xp OS.

I love Ubuntu!!!

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

What file are you downloading, exactly? Please include the download link you are using. – Eliah Kagan Jul 23 '13 at 17:04
Are you trying to install Ubuntu with Wubi? – papukaija Jul 23 '13 at 17:20
To install Ubuntu 12.04 inside Windows, so that no new partitions are created and it's not necessary to boot from a live CD/DVD/USB to perform the installation, you should use Wubi. For information on how to do this, see Wubi's download page, this tag wiki, the Wubi guide, this thread (once the forums are back up) and/or Can I install 12.04 inside Windows?. – Eliah Kagan Jul 24 '13 at 14:24

I think that you must be downloading the LiveCD version of Ubuntu Desktop. This can not be run under windows, you have to burn it to CD, then reboot your computer.

If your BIOS is correctly set up with the CD/DVD drive as the first boot option, then Ubuntu will start and allow you to install it alongside your version of Windows.
