i dont think it's viruses
since i just download it again
and i do clean install enderal, and not backup version
anyway i do already fixed the problem
so i just zip the exe that not changed with installation version, then after enderal installed i just overwrite the exe with the zip one
it's need zipped or otherwise even the tesv.exe place elsewhere it will get changed too
so yeah, when the exe changed, i just overwrite it for now, it's at least fix i can do for now, and the important i finally can play this mod
im really thank you to you all, especially hoxyd that give me fixed launcher so i can update enderal
thank you ^__^
