Hi, since this cost me some time and others might run into the same trouble... Context: kubuntu (here in 64bit-mode on an Athlon64 X2, but seen also in 32bit-mode). I'm using VMWare Player quite a lot. After a kernel upgrade, I also had to reinstall the player - but it wouldn't properly start, saying that I needed to run /usr/bin/vmware-config.pl - which would fail while shutting down all services etc. In the end, the issue is rather trivial - the installation of the player leaves a file "/etc/vmware/not_configured" even though everything is configured as it should be. It is sufficient to rename or delete the file, and vmplayer will run. hth, Eric
