Hey Schmiddy,
Thanks for contacting NI. I believe the cause is that you may not have full support from the Vision Development Module installed for LabWindows/CVI. Could you do a repair on this installation through Add/Remove Programs to confirm this? If you add support, your functions should show up. Additionally, you mention that you are missing functions from the "image management" function tree. Do you have access to any more functions other than the image management tree?
I will wait to hear back from you
Take Care,
