Then I must have done something wrong. I will try it again. I tried to install the guest pack in the F.M. I will try to do it from a terminal if I can figure out the commands. From the F.M. the term runs so fast that I can not read it so I assumed that it installed correctly. This is my error.
EDIT: The guest pack I am installing is in the VB CD/DVD drive, will this make a difference? Thank you for your patients with me.
Before starting the VM, I set the CD/DVD drive to pass through mode... so it shows as
Empty, and attached to
IDE Secondary.

Then with the
VM running, I click on
Devices --> Install Guest Additions...
An icon for the CD/DVD appears on the desktop along with a message box;

I choose
Allow Auto-Run and the terminal shown in the
last reply appears, and runs the installation script. I do
nothing and
wait as the script does the removal of the old Guest Additions and installs the new version, then press the
Enter/Return key when it's indicated to do so. The rest is as spelled out previously, shut down the VM, reboot, then choose the
Auto-resize option.
The last item of business is to click on
Devices --> CD/DVD Devices --> Remove disk from virtual drive.

To return the
CD/DVD device to a
normal usable state, check the
Host Drive <whatever> box in
Devices --> CD/DVD Devices.
