Interface rhino in 2 languages

HI , I have installed rhino WIP.

it automacally switched to italian even if RH8 was set in english + RH WIP ENG was downloaded

i acted on the options to set it in english , everything updated but the template window is still italian

What is the path in Options>Files>Template files pointing to? It may still be pointing to the it-IT Italian localization folder, you may need to change it to the en-US folder.
