When I tried to update calibre to version 0.7.48, I received a Windows Installer error that says ...

"This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package."

I've never had this problem before downloading updates. Has anyone else had this problem. I'm using a HP laptop running Windows 7.
