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.
Thanks a lot.
A life saver...
It seems that 2 years after your post, no one in cadence thinks its important enough not to override major system variables!
