VN How to run vn on Kirikiroid2 which have sig + plugin folder

[Realsliver1234]

So basically I’m using Kirikiroid2 and whenever I try to play a vn that has an xp3 file along with sig + plugins folder it just doesn’t work and says “startup failed: corrupted execution file” on vn like ljimekko ni Okasareru Boku no Ane and Ochiru Hitozum. Any help would be appreciated
