I downloaded the pre-built binary and while I did read that it was a pre-build binary, my brain didn't exactly connect the dots and I tried to use it as if it were an installer. Took me a good few minutes before the "Oooohhhhh!" moment finally came.
I'm not sure if this is possible, but when double clicking jtd-infer.exe a terminal/command-prompt window opens and it's blank. Perhaps a message could be added there?
Either way, thanks for this tool. Works like a charm!
