I could near guaruntee that you didnt get that from itch.io, and if you did then you downloaded it from a copy/ impersonating game that stole images/content from this game by stealing the files and reuploading them differently with their own code involved.
I don't know where that SetupReiPatcherAndAutoTranslator.exe came about, I found it with a fire velvet during the game, and it was shown that there was only one before, whether it was because it had something to do with me in China
I downloaded it again.,Now there's only one file reported as a Trojan.,But this zip file suddenly reported an error.,Now I'm deleting and can't delete it.,I can't open it.,Delete prompts me to have no permission.
