If you can't start *.msi files on your (old) system, than you don't have Microsoft Windows Installer. In that case, install Microsoft Windows Installer before Internet Radar.
It can be found at:
Windows Installer for Windows 95, 98, Me
Windows Installer for Windows NT 4.0, 2000
Important: download Windows Installer only if the installation of InternetRadar failed !

After installation restart Internet Explorer.

There are local versions of Internet Radar on different languages and they are more powerful than English version, because they are also used for site traffic metering of all sites on local language - something like local Alexa service.

Serbian version
