I found this on http://www.solo-technology.com/blog/2009/10/29/vmware-player-3-0-and-net…
The vmnetcfg.exe is included in the installer, but won’t be installed.
1. Run the installer with /e option. For example:
VMware-player-3.0.0-197124.exe /e .\extract
All contents will be extracted to “extract” folder.
2. Open “network.cab” and copy vmnetcfg.exe to your installation folder,
typically “C:\Program Files\VMware\VMware Player\”.
