CVI installs DataSocket, so it should appear in that list. Do you have the directory
CVI80\toolslib\datasock, with the .h, .lib, and .fp files? Can you run the DataSocket samples, or any other program that uses DataSocket? If so, do you have the file
Program Files\National Instruments\Shared\MDF\Manifests\NI DataSocket {46ADF464-9D63-47E0-B59F-0D9C3A60B4C4}.xml? One other thing to check: from the Windows Add/Remove Programs, find National Instruments Software, then click the Change/Remove button. From the list that comes up, find NI LabWindows/CV 8.0.x FDS Package, then click the Modify button. This should give you a list of all the installed features. Press Ctrl+Shift+A to show all the components installed. Near the top, make sure you see that
Datasocket and
MDF Support have green check marks.
Let me know what you find.
