Unable to find Busybox to program board?

[BitCorrupted]

I'm trying to set up STM32Duino on a Win64 machine, running the V1 IDE, to program an STM32 board, but I keep getting an error that the programmer can't find busybox? I checked in the STM32Tools directory and there seems to be a copy of busybox in there... Any ideas as to what's causing the error?
This error is also being caused on Linux somehow (even though Busybox is a core system component there!) but I'd like to investigate Win64 first

Hi @BitCorrupted
It seems you used Arduino IDE 1.8.x.
As stated only Arduino IDE 2.x is now supported.

That explains it. Thank you!
