Installed Orcad demo and now Oracle VirtualBox is redirected to C:\SPB_data instead of c:\users\owner.VirtualBox.
This killed my virtual machine firmware development environment.
C:\SPB_data directory did not exist until the OrCAD install.
It appears I am not alone
Here is a similar post on VirtualBox site. Their suggested solution does not work. This is an OrCAD install issue, that has become a VirtualBox problem.
