The VMware Tools are not running in the virtual machine

Here is what I did:

1. start the vm

2. "/Applications/VMWare Fusion.app/Contents/Library/vmrun" -gu user_id -gp "password" runProgramInGuest "/Users/Shared/VM/my.vmwarevm/my.vmx" "/Users/user_id/scripts/script.sh"

then i received an error:

Error: The VMware Tools are not running in the virtual machine: /Users/Shared/VM/my.vmwarevm/my.vmx

The target OS is Mac OS.

How can I debug this problem?

Thanks
