I encountered the same. Searching this forum gave me some work-around and I had got it installed finally.
Installation hangs at about 62% that is when you had to move away the file /etc/vmware/database to /etc/vmware/database.bak & also delete /etc/vmware/database.lck then the slow painful process of installation will continue. Then after it is done you need to move back /etc/vmware/database.bak to /etc/vmware/database
basically that will do, but accordinng to what I searched here, I also run an install-all script, however I think that step will be automatically done when you run workstation.
