Sorry, I was confused because you posted in the Wokstation forum.
Anyway, the VMware Player installation should have created a virtual network adapter (VMnet8) on the host with 192.168.91.1 in your case. You can check this by e.g. running ipconfig /all on the host's command line. This network adapter exists independently of whether the host is online or offline, so you will always be able to communicate between the host and the guest. Btw. which VMware Player version do you use?
