What kind of trial do you offer?
An awesome one. Path Finder offers a completely unrestricted free trial for 30 days. The trial counts days of actual use. If you only open Path Finder once, you'll have 29 days remaining in the trial the next day that you launch it.
Path Finder is a powerful tool with tons of features, so we
understand it can take a while to get acclimated.
This also works around one of the more annoying things about time-specific demos - you may often find yourself downloading an application, launching it once, then getting too busy to play with it until after the demo has already expired.
