Hi, I installed Windows 10 VMs (VMware) into the Host OS. While starting Win 10VM with NAT adaptor, it works well. 

In my GNS3 app, I can't link (add) a Win10 VM with a NAT adaptor. The error appears in my GNS3 application if I select the NAT adapter (Attachment NAT is already configured). So I changed the network adaptor option to VMNet1 or VMNet2 (host only).  

The issue is to select VMNet 2; there is no network adapter in the Win10 VM.

I have already set up VMware network adapters on my host operating system.

I have no idea what to do about it.
