Lotus Smartsuite 9.7 will not work on Windows 7 and Windows 8 because of the problems caused by the installer. Basically, the installer cannot detect space and memory although you have plenty of it. Lotus Smartsuite 9.8.x is suggested to work on Windows XP and even on Windows 7. Windows 8 works pretty much the same as Windows 7, so it's a chance that it will work using compatibility settings. Practically, you will need another installers for the application but the only way to obtain it is to get a new version of the main product.
