Are you sure you really need VMware Tools? It's long time since I installed VMware Tools on a linux guest and I never missed them. Either I install open-vm-tools package (which is available in the distribution) but often not even that.
opensuse 15.1 is the host not the guest. The workstation pro 15 install on opensuse 15.1 with a windows guest prompts for vmtools download. and i don't think you can install open vmtools on windows guests.
