VMware unable to open network mapping library

When starting a VM, I received this error: 
VMware unable to open network mapping library
This started when I moved back to VMware Workstation 6 after trying Server 2.0 Beta.

This thread got me to thinking, but didn't fix the problem.

I looked further into the .vmx file and found more entries that Server 2.0 beta had added. The removal of these 4 lines fixed the issue and the VM now starts fine in Workstation. 

ethernet0.features = "1"
ethernet0.networkName = "Bridged"
ethernet0.allowGuestConnectionControl = "FALSE"
ethernet0.wakeOnPcktRcv = "FALSE"

    Your post pointed me in the right direction I just removed everything referring to ethernet0 and added a new NIC.

    Thanks that really worked out beautifully. You came top of the google search for this; rightly so! You do have to enable Ethernet again after editing the file and loading it into WorkStation. Otherwise you'll have no network!

    Also fixed network issue with my laptop and vmware too. Could not create a network but deleted all lines referring to ethernet 0 and now works. Thanks.

    Thank goodness for your website! I took a VM from VMWare Server 2 down to VMWare Workstation 5.5 and it was initially giving the "unable to open network mapping library error". It started working perfectly after I removed the lines you mentioned from the .vmx file.
