    I am running 64-bit Win7, I downloaded the 64-bit "msi" installation file, but when I double click it to install, a message pops up saying "This intsllation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package."

    I also noted that Publisher shows "publisher unknown", and suppose this may have caused the problem. Any idea how to by-pass this message and install in W7?

    First time I downloaded it from www.download.com, and it was an "msi" file that I wasn't able to install.
    Today I tried a download from sourceforge, it was an "exe" file, and it worked! Thanks for the advise.
