If you are saying that vmware-tools are not getting mounted then please follow these steps for manual installation of tools:
1. Click on Install VMwareTools
2. Inside the guest ie. FC8 type "mount /dev/cdrom /media/cdrom" on the terminal
3. If "/media/cdrom" mountpoint is not present create any temporory mount point eg. "mkdir /cdrom ; mount /dev/cdrom /cdrom"
4.Goto "/media/cdrom" and here you will find the installer files ie. rpm or tar installer.
