Troubleshoot problems with "Reinstall Vmware-tools" gray and cannot be installed

Reinstall the system a few days ago, after the virtual machine needs to be re-installed, installed to use Vmware-tools to achieve file sharing, but found that the virtual machine is grayed out, unable to install the Vmware-tools, in the shared folder where the shared folder set up the monkey also no use,/ There is nothing in the MNT directory.

Here's how to fix it:

Although reinstalling the VMware tools display is grayed out, there is linux.iso in the virtual machine's download package, which is what we need.

We need to install on Linux, the steps are as follows:
1. Mount the image file, virtual machine, settings--hardware->cd/dvd. Under "Connect", select "Use iOS image file", browse to select the virtual machine package directory under Linux.iso

2. After the mount succeeds, in the lower right corner of the virtual machine CD/DVD, click on the icon to select "Connect". So I can see the disc file on my CentOS7 desktop.

3. Open the disc file, the folder has the name of vmwaretools............tar.gz compression package, click on the Unzip button above "extract", browse to select the directory to be extracted to, here is the Home/documents directory selected, Start unpacking.
4. Open the Terminal interface, enter the CD Documents/vmware-tools-distrib carriage return, and then enter sudo./vmware-install.pl Enter, you may need to input yes in the future, continue to return, restart the virtual machine.
Now look at the/mnt directory, the folder already exists Hgfs

Set up a shared folder there

Can see HGFS below is the shared folder we set up
