Install VMWare on Linux 64 bit full procedure
These are instructions for RHEL based x64 Linux (CentOS 5 x64 in my case).
Make sure you update to the latest available kernel;
yum update kernel
Make sure you have installed all requirements (is really needed if you have a minimal install);
yum update glibc
yum install gcc xinetd kernel-devel libXtst-devel libXrender-devel
rpm -qa kernel
Remove old kernel with
rpm -e kernel-2.6.18-53.el5
Download VMware (tarball);
Unpack & install;
tar zxf VMware-server-1.0.4-56528.tar.gz
Take all suggested settings and locations, should be fine. Get a serial from the VMware site, you need it during the config.
