The company behind TreeSize has axed support for its perpetual licenses, compelling users to switch to a subscription model. This move has left long-time customers feeling sidelined, especially after losing access to update and support.

Since 2025, JAM Software has been phasing out traditional perpetual licensing for TreeSize editions in favour of subscription-based models. Perpetual licenses are now only sold for personal use, offering a one-year window of updates and support before users must subscribe or risk losing access to critical features.

One Reddit user expressed frustration, saying: 'Honestly, it feels quite low to strip paying customers of the ability to simply download the installer for a software version they already paid for.' While JAM Software’s Hendrik Christ explained that the change was necessary due to economic conditions, many users feel their purchasing power has been undermined.

Even more exasperating is the fact that JAM won't provide backup installation files or license keys to customers with unsupported perpetual licenses. 'Older software versions can contain known bugs or even security vulnerabilities,' said Christ, justifying this decision despite user concerns about losing access to their own legally purchased software.

The transition from a one-time purchase model to subscription has disrupted the expectations of many long-term TreeSize users who now find themselves caught in a support limbo. As JAM Software continues its shift towards subscriptions, the future for perpetual license holders remains uncertain.
