and license keys, as support may require proof of purchase to recover codes for older versions. Official Support:

: Hosts a safe history of SolSuite for Windows, allowing you to select specific version numbers if the latest update has bugs on your machine.

If you purchased SolSuite in the past, check your old emails or CD cases for a registration key. The same key often works across multiple major versions. Without a key, old versions will run in “trial mode” (usually limited to 30 days or a few games).

SolSuite is shareware. If you purchased a license key in 2010, it may not work for the 2024 version, and conversely, a modern license key will not unlock a 2010 version. Ensure you have the correct registration key for the specific version you are trying to use, or be prepared to play the trial mode (which usually limits the number of deals you can play).
