I have a software installer for WinTR-55 v2.0.0 (16 July 2022). But I don't know where it came from. USDA NRCS says the current version of WinTR-55 is 1.00.10 which is 13 years old. The only reference I can find for WinTR-55 v2 is from HydroCAD which is a separate product.
So I'd like to know whether WinTR-55 v2 is a legit version. Was it released and yanked, or is it secretly available somewhere? Working in IT, just need to make sure I'm supplying the correct software to our engineers.
