Use the vi library manager and copy the vi into the user.lib folder restart labview (close and reopen) then it will be there.
the user.lib folder is under C:\Program Files\National Instruments\LabVIEW 7.x\user.lib. Or if you knew exactly which function on the pallette all you have to do is find the folder for that function and find the lib for it and open it then copy it into there. again using vi library manager.
