Hello! Had to message you here since you don't have anonymous messaging in your Nitro Chiral account (unless you do and I didn't see, in that case I'm sorry!!) but you can download Lamento patched into English using this link! https://archive.org/details/lamento_btv
It is 100% safe as it was uploaded by a member of the community (@ denpaarchivist) here on twitter. Just make sure to set your system locale to Japanese before installing anything which is very easy to do and you can find guides for that online.
A lot of people haven't played Lamento because of the old installation method and it's also NC's longest VN so I get very excited when someone shows interest in it. I hope you can download it without trouble ^^
And one last thing: Nitroplus' older games run in very uh... Unstable engines. So make sure to always save before fiddling with the menu and settings. It can crash if you spend too much time in there for some reason. It runs on my Windows 11 machine too! Good luck and have a good day!
