Thank you all for responding to my question in regard to Realview's inability to operate on my system.  It appears the hard drive is the culprit as I have a Nvidia GE Force 8500 GT.  I contacted HP and they recommended a Nvidia Quadro 1800 FX.  Now, one more question.  I am using a student version that I won thru a scholarship.  Other than student version being printed on the prints, are there any other restrictions to the student version?  Could the inability of realview to operate be one?Thank you and I look forward to your response.
