I just tested this under Windows 8 Enterprise using VMware Workstation 9.0.2 and it worked as expected.
I added VMnet2, change the IP Address/Subnet Mask from the default to the values you show, unchecked "Connect a Host..." then clicked Apply and OK. Reopened VNE and it was as I set it. Also checked the corresponding .conf files and Windows Registry entries and all was as it's supposed to be.
Sorry I don't have a specific answer for you however wanted you to know that is does work as expected, on my system at least.
