Yes, I do know which Kees have to be gotten rid of to reset the trial period:
On XP and previous: HKLM/Software/Chariot Software Group/App-specific kry(s)
On vista and above: HKEY_CLASSES_ROOT/VirtualStore/Machine/Software/Chariot Software Croup/ app-specific key(s)
If they exist, the trial counts down, if they don’t exist the trial resets to 30 days and effectively de-registers the product(s). I would love to build a key generator for these apps but that might take awhile as my budget just got a squeeze put on it. Long story, so for now I’ll have to build a trial reset until I can pay to outsource the building of a key generator
