Please help me open itunes! This is getting ridiculous.

Question

This is the third time I've posted this... no one has answered so far... and I've been without iTunes for over a week now!!!
When trying to open iTunes, a dialog box opens up with the caption "*iTunes Setup Assistant*", and header line "*Download Album Artwork*" which tells me how I can go to the iTunes store and get album artwork from there.
Included in this dialog box are two buttons to choose from: "Next" and "Cancel". I have tried clicking on both of these, to no avail. Nothing happens at all, and I cannot close down the box with the "x" in the top left hand corner either.
After a short while (and a whirrring noise from my frozen laptop), another smaller dialog box opens up with the caption: "*Upgrade Available*", detailing: "*A new version of the Qloud plug-in for iTunes (3.0.1090) is available. Click OK to upgrade*". I am offered two buttons: "OK" and "Cancel". Nothing happens when I click on either of these buttons, except that annoying "blink" sound that means 'nothing doing'.
The dialog box appears in front of every window, and cannot be moved out of the way. The only way to close it is to "End Task" through the Windows Task Manager.
iTunes will not open even after re-booting! Reluctantly, I removed the iTunes and the Quick Time programs from the computer, rebooted, and re-installed iTunes, but the bug is STILL there. I've repeated this, pointlessly, about three or four times. The same thing still happens. It's really upsetting not to be able to open my iTunes library, or update my iPod!
Please help!

Answer 1

What version of the Mac operating system is installed on your MacBook? To find this information, go to the Apple menu, select About this Mac and look where it says version.
iTunes 11.0.1 requires Mac OS X 10.6.8 or later, so if you want to use your iPhone with your MacBook, you will need to update the OS on the MacBook at least that far.
You can purchase 10.6.8 on disk from Apple for $20 (in the USA.)
If you want to get a more recent OS, let us know what the specs on your MacBook are, we'll tell you what you can get.
Best of luck.
