I have tried to reinstall ist multiple times. The installer itself mentioned never any kind of error. I also tried to install it in another path, but there are also only these two folders.
Well, i´ve tried everything that could possible help. I also thought, that my windows was broken, so I repaired it. Even a new installation of windows won´t help. So I have absolutely no idea what the problem is. It only installs everytime the two folders, nothing more. The photos or videos which are used in the game are visible to me. So under subfolders like BE or so I can find these pics or vids. There is nowhere any exe or else. I have also downloaded and tried it multiple times. The only thing I remember is, that a few versions ago the program installs perfectly. But now the new versions won´t work.
