I didn't find version 6 of the ISM application, but you have the possibility to download the Basic version in 32 or 64-bit working mode. The download is listed on their official website and based on their buying model, you will have the possibility to upgrade from within the application. Visit the page and then save the installation package that corresponds to the architecture model of your OS installation. You can also get in touch with the developers of the application through their Contact Us page provided on the same website.
