Hello Guy
I am chilean (spanish) speaker that speaks no dutch and lives near Rotterdam.
As for your question.
When you install vagrant, its the best let it install on the default path.
c:\hashicorp\vagrant
then, your user need to have permissions on 3 directories.
say your user is guy
your home will be
c:\Users\Guy
The base directory for vagrant base boxes (templates) will be
c:\Users\Guy\.vagrant.d
Any VirtualBox you create will be stored here:
c:\Users\VirtualBox VMs
Then, you can have a project in any directory, in your case seems on d:\ drive.
I will say, please start easy and confirm all works:
c:
cd c:\Users\<user>
mkdir precise64
cd precise64
vagrant init -m hashicorp/precise64
vagrant up
^ does that works?
Thanks
Alvaro.
