Test cases:

3. Computer has lower versions of Vbox & Vgrant - Pass
4. When install, re-install, you may get the error:
"Vagrant could not detect VirtualBox! Make sure VirtualBox is properly installed. 
Vagrant uses the VBoxManage binary that ships with VirtualBox, and requires this to be available on the PATH. 
If VirtualBox is installed, please find the VBoxManage binary and add it to the PATH environmental variable."

Please make sure Virtualbox path alway stands in Path of OS. - Need update
