If you click on Browse -> Show VI Hierarchy and then View -> Full VI Path in Label, you can see all sub vi's and their paths. Since you just upgraded to LV7, I would guess that some of the sub vi's are coming from previous version of LV. Did you have Report Genreation Tools in the old version, but did not install in LV7? The message about sub vi was not found at ... was loaded from... means that the sub vi was not found where it was expected to be (from that last time you ran the vi in older LV version). But LV searched and found the sub vi at a different location. When upgrading, the sub vi's under an old directory, like LabVIEW6.1, might not be there anymore, and the vi is now found under LabVIEW 7.0 directory. In this case, the message is valid and there
is nothing to worry about. Save your main vi so that the new paths to sub vi's will be established and saved. In some cases, you may have to manually replace sub vi's in old paths with the same vi in a newer LV7 path. Once you have substituted all sub vi's with the ones from the right path, save your main vi and all sub vi's.
