download not working.

I have Windows XP. When I download your program, nothing happens. When I locate it on the computer and attempt to run it, I get a message: "The installation package could not be opened. Contact the application vendor to verify that this is a valid Windows installer package."
How do I download your program?

Please go to www.primopdf.com and download the installation file again. Your file could have been corrupted or incomplete.
