What is a ‘Lifetime license’?
A ‘Lifetime license’ is a one-time purchase for the version purchased. For example, if you purchased a lifetime license for Fences 4, it would be a one-time fee and you would receive Minor updates for that version’s ‘lifetime’ (4.1, 4.2, etc).
However, unlike subscription versions of select products, you will not receive Major updates (4 → 5 → 6 etc) at no charge.
Business customers have multiple options that can be either non-reoccurring or reoccurring, depending on their preference. Please contact Corporate Sales for additional information about how each product is licensed.
Do know that version your purchase will work forever as long as the user do not upgrade to a Windows version that no longer work with that version you purchase. For Example. Fences 4 should work forever as long as the user is using Windows 10 or 11 that are compatible with Fences 4. For now, Fences 4 work with Windows 11 v23H2. Unless Microsoft do a major changes on Windows 11 in the future, it is safe to say Fences 4 work on Windows 11.
