Hi Malware, and welcome to the site!
What is the "trigger finger", is that the product name? If so, then it's not a FingerWorks product, and we can't really help you here, sorry.
This page lists the product names of FingerWorks - do you mean any of those instead?bin/view/Main/FingerWorks
If you're talking about a FingerWorks product, then they work fine without software - that's only needed for changing the configuration but out-of-the-box the configuration is very good to start with. And the software is freely downloadable for any major platform.
