Error installing SQLite ADO.NET on Win 7
Well I am having exactly the same problem,
but the issue is b/c Installer.exe requires a command line argument, called "-confirm"
They made this to make the exe not install when just double clicked.
So pls try following command from command line
Installer -confirm true
