Unzip the tarball (I used 7zip but)
Open VMX file with VMware player
start the VM
click into console window
when 'press ctl-c' message appears press ctrl-c
in menu select 4 to wipe disks
after disk wipe is finished you should have a usable simulator. That procedure is described in the installation PDF. I've done this several times in the past for different versions of the simulator (using VMware Workstation 9/10 or ESXi 5.1 where an additional step to convert the unsupported disk format is needed).
I never had to do any changes to the VMX file (well if I convert the split VMDK data file which contains the disk images into one big file I hve to tell the system to use that one but that's just remove hard drive 4 and add preexisting file as hard drive 4 type ide)
Which version of the simulator are you trying to use ? whats the file name (there are 4 files for 7m/cm and VMware Workstation/ESXi)? Are you running Linux or Windows ? You are running Player 6 on Windows 7?
