I use Windows 7 and tried to update my old Calibre as directed on the website. "Simply un-install calibre and install 3.48...which works with all Windows 7/Vista machines, from here." Foolishly, I uninstalled the old, then downloaded the new, which failed to install:
"This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package."
There is no email address or link on the Calibre website to contact Calibre. How do I get Calibre back on my Windows 7?
