An irritating error message appears every time I try to install software on my computer system. It is not merely happening with one application but with all. I have tried to install Adobe 9, Google Earth, etc. etc., but at the end of the installation process, an error message occurred which says,

Error:

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.
