Problem with WEFAX in Vista

Hello Friends,

I'm running Windows Vista on my system. The problem is that i'm unable to load eFax software on my pc. Whenever i try to install it gives me the following error message that "eFax Messenger can not be installed on Windows XP/Vista." Can any one tell me why i'm unable to load eFax software on my pc? Does any body have any idea about this issue? Any help on this issue would be appreciated.

Thanks a lot
