Unable to run vagrant up due to Vbox error (MS 81.)
vagrant, virtualbox, windows, windows-8.1
Solution
I bet that you're using the latest VirtualBox version (4.3.12). If so, there's a known issue which will be addressed in Vagrant 1.6.3:

As a workaround you can install VirtualBox 4.3.10 and it will work flawlessly.
Problem
I am on Windows 8.1 When i attempt to install vagrant and run it with virtual box i always get the following error. "The provider 'virtualbox' that was requested to back the machine 'default' is reporting that it isn't usable on this system. The reason is shown below: 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." I have tried different things such as uninstalling both virtual box and vagrant and re-installing them. I have tried installing vagrant first then vbox and the other way around also but no change. I am new to vagrant so if anyone can assist please.
