Network Settings options greyed out in Fusion Pro 7.1.0

This post was originally published on this site

I have uninstalled VMware Fusion 7.1.0 Professional edition 3 times, emptied trash deleted all settings files as listed in KB article 1017838

 

installed Fusion 7.1.0 .. it somehow still gets my license keys and vminventory and when i go to Preferences > Network .. unlock to make changes but the entire settings area is still greyed out.

 

any clues or ideas on getting this fixed?
