This version can be used on up to 3 computers in a home setting, gets updates for 12 months, support via forum, and continues to work in whatever ability the final version within the 12 months of support has for as long as you want. Update only when you need new features. I've been using an old Aida32 for about 10 years I think, still grabs most of what I want, management of licenses.
