I used Memorex Expressit on my computer running XP. I just upgraded to a Windows 8 computer. It appears that this will not work.
According to the compatibility page from Microsoft, this application is not compatible with operating systems above Windows XP. In other words, the latest version of the application is compatible up to Windows XP only.
exPressit SE 3.1 will run on Windows 8, but seems to be more complicated that Memorex's versions. It does offer a bigger selection of label formats than the older versions though.
