@Jedpog(View Post) Are you unable to launch Powder.exe? If that launches for you, you should definitely use it, Powder-legacy.exe isn't supported (and in fact had a pretty serious bug in particle movement for some unknown reason). Powder.exe could also be faster.
Powder-legacy.exe is for older computers, and by that I mean like 10+ years old and probably still has XP. Since TPT probably barely runs on those types of computers, and supporting both was complicated/added a lot of unnecessary compile time, I removed it.
If you still need Powder-legacy.exe just say so, I compiled one for someone a few months ago and could go find it.
@Jedpog(View Post) Can you be more descriptive? Does anything happen when you double click it? If the legacy version still doesn't work, then that likely wasn't the issue. Either that or it really isn't legacy (I think it is though? Unless I compiled it wrong. I used visual studio)
