i just installed frespire on my pc , at the first screen before a install i chose with F2 spanish as my native language y filled all the paramethers the install wizard asked when it finished i end up with a freespire well installed but in english, i went to the regional setting and i tried to change it to spanish with no luck at all, can anyone be so kind to help me or tell me how can i make it work in spanish?

i forgot to say what the system gives when i push install a new language "Command 'qt-language-selector --mode install' not found."
