I tried to install the examples to c:\vdf\18.0\examples

c:\vdf existed, but c:\vdf\18.0 and c:\vdf\18.0\examples didn't.

Unfortunately I fat Fingered the folder name and entered " C:\;\vdf\18.0\examples"

Really screwed the pooch.

They still didn't exist after the installation, and I didn't get an error for entering a stupid path.
