Which installer file did you use?

---

i used yEd-3.16.2.1_with-JRE_64-bit_setup.exe. but also the 32-bit version first. Both gave  the same errors and problems. It took both installers quite some time to reach the point where they started to install the files. Then a message came, that the installer had no rights to change the  Program Files folder and that hinted me to rerun the installer as an administrator and then everything went flawless! So I managed to install yEd eventually! Thanks for responding anyway.
