I did try install a supervisor (GE FANUC iFix 4.5 / 5.0) software in a Windows guest system,

And I has back this message (in Windows blue screen):

aksfrigde.sys

Did you google it? http://www.google.nl/search?hl=nl&q=bso ... eken&meta=

I still looking for solution.

I guess, this is a problem with VB USB driver.
When you need use a HASP hard key or similar VB crashes.
