I am using a LabVIEW VI to run two Opteon digital cameras. Originally, they were run off a Windows NT machine, however it ran out of hard drive space and we had to upgrade to a Windows XP machine. I installed all the new drivers from Opteon, however when I run the VI on the new system it does not load the image viewer or scroll bars and I recieve the error "could not load control". The control for the view screen is "MVCamView" and the control for the scrollbars is "MSForms.IScrollbar". The drivers sent to me by Opteon work fine, as the free program that Opteon sent has no problems.
