It has nothing to do with antivirus i seem to have found the solutio. idk why after a while the Pokemon Exe is removed and i have to redownload but, i extracted it in the download folder. and for that it would not work. even tho i am administrator it would not let me unpack there. So i made a new Folder on desktop and it works. Still after 2 or 3 uses of the game i have to redownload another zipfile.
