Installing VMware Workstation on a Windows workstation isn't hard to do; just run the installation file and change a few of the default parameters and it will work. The installation of VMware on Linux is a bit more difficult because you'll have to run a few commands from a shell environment.
64 or 32 bits?
If you're using VMware on Linux, you should install a 64-bit flavour of Linux. The handling of hardware resources, especially memory, is much more efficient on a 64-bit Linux version than it is on a 32-bit version of Linux. So for the best possible performance, make sure to use the 64-bit Linux version.
