Thanks, Gi-Sung,
I will run the installer again, but I recall that we tried once already with Windows 8 compatibility set, and the failure was the same as with Windows 7 compatibility (InstallAnywhere quit after the initial loading progress bar).
The IQ 16.0 distribution we have contains only the \ms-redist-2010 subdirectory under \archives; the other two earlier versions are not present. I will investigate whether these distributions can be loaded from another source.
We are also verifying the distribution level of IQ 16.0
