I received the following message after trying to upgrade to 8.0

"The iTunes application could not be opened. A required iTunes component is not installed. Please repair or reinstall iTunes. (-42404)"

Any help would be appreciated, I can't launch the program currently....

Emachines, Windows 98

    What operating system are you using, it can't be Windows 98 if you have been using iTunes.

    Was there any more information in the error message? It would be helpful to know which component is missing.

    Could you try launching QUicktime? Does it work normally? iTunes will not work without QUicktime. It might be a QUicktime install problem rather than an iTunes problem.

    I left it to download last night... so I clicked on the Apple Software Update and went through it again - updating Quicktime and Itunes together. Now I'm getting a message "Itunes can not run because some of its required files are missing. Please reinstall Itunes"

    My concern with reinstalling is that I will lose everything I had in Itunes and how I had it set up.

    Any thoughts? And your right, I'm running Windows 2000

    The last iTunes version that is compatible with Windows 2000 is 7.3

    You need to download the windows 2000 version

    Then uninstall all the iTunes related programs listed in this article which is actually for XP:

    Then install the 2000 compatible iTunes.

    If you get a message about a later version library when you try to start iTunes, you have to recreate the library from the xml file:

    I am afraid if you want iTunes 8 you will have to ugrade your operating system or get a new PC.

    Thank you so much for the guidance... will I lose my library or will it come back?

    You should not loose your library as long as you do not delete the iTunes and iTunes Music folders in your Music folder.

    How ever it is always wise to have backups.

    AS I indicated in my first post may have to recreate your library because you are down grading. But you may not have to do that as iTunes did not run.
