I need help with trying to load a google earth and Itunes on to my computer.When I download the programs on to my laptop then double click on the icons to download the program it start up going through it`s normal process but then the process stops and a message comes up which says:

THIS INSTALLATION PACKAGE COULD NOT BE OPENED-VERIFY THAT THE PACKAGE EXISTS AND THAT YOU CAN ACCESS IT, OR CONTACT THE APPLICATION VENDOR TO VERIFY THAT THIS IS A VALID WINDOWS INSTALLER PACKAGE

I have downloaded both program on a different computer then saved it to cd but even this did not work it came up with the same message

With Vista it's a good idea to right click on the installer and select "Run as administrator".

I've installed the latest version of iTunes on several computers without any problems.
Google Earth, OTOH, fought me tooth and nail before I got it installed - not a real pleasant experience. It took a lot of googling to get it to work correctly!

I tried to run as administrator I got the same result the same message was displayed

Could it have been corrupted during the download? If you're in dialup, don't do any other Internet things while downloading a large program or it could end up mangled.

thanks for the advice but I am on cable and not on dial up I have tried loading without anything else running but still get the same result

did you ever figure out how to solve our itunes download problem? I have the same situation..running Vista and tried to run the file as the administrator with no luck.
