I think there may be a bug in the OpenG utility "ogpatch_librarian_bugfix-1.0-1". I believe this is intended to rename the VI "Copy From Folder to Folder" in vi.lib\Utilities\libraryn.llb (by adding the suffix "__buggy") and replace it with a VI of the same name that corrects a race condition issue. I've got more than half-a-dozen Windows XP machines (some "real", some VMs running on Windows 7 PCs) that are running LabVIEW 7.0, and using VIPM 3.0 or VIPM 2010 to install the OpenG packages. In most cases, the installations are a year old (or older), and haven't been updated (i.e. no new packages have been added). In all but two cases, it appears that an error occurred during the package installation (and either not noticed or simply ignored, as VIPM didn't "complain loudly"), the net result being that Copy From Folder to Folder was simply deleted from libraryn.llb, and not replaced. In a number of cases, this "missing file" was not noticed, and the user was none-the-wiser. However, when I attempted to use the Application Builder to create an executable (from any code, even from a simple While Loop with a Stop button inside), I would get an Error 1003 with a message referring to a protected file in the App Builder. It turned out, however, that the real error was the missing Copy From Folder to Folder VI (another example of a misleading error message!). I've tried to duplicate this bug by taking an existing VM, cloning it, removing LabVIEW 7.0, VIPM, and OpenG, and then reinstalling them as I usually do. I was not able to reproduce the error -- the Librarian Bugfix Patch worked, replacing and renaming the VI in libraryn.llb. So I don't have a "smoking gun" proving that this patch is, itself, buggy, but the fact that most of the LabVIEW 7.0/OpenG installations I've examined have (a) a missing file in libraryn.llb, (b) an indication that VIPM has installed all the OpenG patches except the Librarian BugFix (and the Notifier BugFix -- hmm, maybe the problem is in the Notifier Bugfix ...), and © there is an Error log with cryptic messages saying that VIPM failed during an installation (though the message doesn't clearly identify what package was being installed). I have left extensive documentation of this issue on the JKI Support Site. I'm following up here in case other LabVIEW 7.0 users might have this "silent" problem. To see if you are affected, simply open the libraryn LLB and see if you have the file Copy From Folder to Folder. If you have 1 copy, then the OpenG patch was never applied. If you have two copies (one with the suffix __buggy), the patch was applied successfully. If you have no copies, the patch failed to install, and may have "clobbered" this VI. A fix is to replace the libraryn.llb file with a "good" copy. Bob Schor
