I am just getting my first turnkey linux setup (LAMP Stack) and am having difficulty installing vmware tools. I went through all the steps in the documentation and had to do the command line installation. The only thing I did differently was that I had to create a directory on /mnt before I could run the mount command.
I remember at the end it ran the configure perl script and then finished successfully. I restarted the system like it said, but when I click the menu at the top it still shows install vmware tools and if I try to launch Unity it says the wmware tools aren't installed.
