I tried it anyway and it had crashed when I woke up, lol.
If you tried it on Windows it crashed while running it in a few hours maybe it crash because you didn't disable the hard disk sleep or anything that could interrupt the software from running. You might need to install dot net core according to their guide.
FinderOuter is great tool/software and more user-friendly. But with lack of GPU support, btcrecover is better choice on most cases.
That's the only downside about this tool but they are planning to add support GPU on version 2.0 according to their roadmap. The only good thing about this tool it's easy to use compared to BTCrecover/Hashcat.
