I've uninstalled the Player as suggested, and the Server RPM installed fine. When I try to run vmware-install.pl I answer all the questions with their defaults and get this: Building the vmnet module. Using 2.6.x kernel build system. make: Entering directory `/tmp/vmware-config1/vmnet-only' make -C /lib/modules/2.6.19-1.2895.fc6/build/include/..
