if you really have vmware workstation 4.5.0 I would recommend getting version 4.5.2. Also, get the vmware-any-any-update90.tar.gz patch.
Alex, Yes, after I get 4.5.2 and the update. it start up ok, but after start a winxp guest operation, it warns that the vmware tools are out of date. Where to get a updated vmware tools
