The most practical solution is to upgrade. The current version of Pinnacle Studio (Pinnacle Studio 26/27 as of this writing) is vastly superior. It supports 4K, 360-degree video, and multi-cam editing.

If you registered your software upon installation, you can often retrieve your key by logging into your Pinnacle customer account under the "Registered Products" section.

If you need help finding your own valid key or installing a legally purchased copy, let me know and I’ll guide you through that process.
