I can not get lubuntu to load. I download file and it tells men "application not found"

What file have you downloaded?

You should download an ISO file from http://releases.ubuntu.com/14.04/ and then:
1. Burn it to a DVD with a burning software (like ImgBurn)
2. Write content to a USB drive using Rufus: http://rufus.akeo.ie/ or Unetbootin: http://unetbootin.sourceforge.net/

Download Lubuntu from: https://help.ubuntu.com/community/Lubuntu/GetLubuntu

Be sure to MD5 test the ISO you download.

You do not need to extract the file, just burn it as an image as slowly as possible.

I am burning my dvd now. Thank you all for your help. Crossing my fingers. I always wanted to be better at this stuff. Perhaps I shall learn.

Unfortunately no matter what I do I cannot get lubutu to load. I have an old Del Compaq which currently has windows xp on it. I have burned the dvd and aI also tried the usb option and I cant get it to boot up from either one. Don't know what to do.

For booting from the CD/DVD, you have to instruct the computer's BIOS to boot from the optical drive.
For doing so you have to press certain Fn-Keys early during the boot process.
If you tell us what make and model your computer is (is it Dell or is it HP Compaq?), we should be able to indicate which key to press.

It says compaq when it first boots up.

If it is a compaq computer, pressing F10 during the boot process (around the moment that the compaq logo os shown) should lead to the BIOS setup dialogue. On these screens you should be able to change the boot sequence to boot from the optical disk, before searching for the operating system on the hard disk.

F10 doesn't work but delete brings up a blue screen with a bunch of options to make changes to my computer. Do I use one of the options in there?

Yes, that seems to be what you need.
There should be an option on one of the screens, with a name like "boot sequence", "boot priority", "device priority" or similar.
To be able to boot from the Ubuntu installation DVD you have to change the sequence of the boot devices in a way that the optical disk, (DVD) comes before the hard disk. (Note, that it might be that the devices are listed by their model name - in that case you have to identify the models of your hard disk(s) and DVD drive(s) first to be able to correctly interpret the output and to set the boot priority.)
