In some situations attempting the installer may appear to do nothing when double-clicked, and if invoked with msiexec /i on the command line may throw the error "This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package." If this occurs, a viable workaround has found to be to create a new .bat file containing the msi install command listed below, and then drag the downloaded msi onto it.
msiexec /i %1
We do not recommend this option, but we have a description of the process.
