Hi again

Apparently, the issue is on the VM side. I unpack the 9.0 VM into the 8.0 
folder, and everything went fine.

Looks like there is an issue on windows when getting the latest 8.0 VM.
Looking the the dev mailing list, I can see a similar issue has been raised, 
when you have unzip program on your computer, that can corrupt the VM 
extraction archive
