It is possible however that you may not be able to insert ther licnese key from the GUI.
In that case go to /usr/lib/vmware/licenses/site and edit the file "license-ws-90-e1-201202" with the text editor you like (e.g. sudo nano license-ws-90-e1-201202) and insert the line:
Serial=XXXXX-XXXXX-XXXXX-XXXXX-XXXXX after the line License Type. save the file and you are licensed forever.

Obviously you need to replace XXX.. with your own serial number. Its been a l ong time since I used a trial version (not saying you have) but you can still elnter the serail number as above You next problem is different and I'll have a look at that but using the above instructions is easier for me than using a slightly complex command linie (which I'm not sure than anybody has veried that it works - it would absolutely have to inser the Serial= linie anyway so that all the information appears in the about screen. If that is not the case its p oor programminig IMIHO.
