I tried pointing version 1.1.1.0665 at LabVIEW v5.1 that is on my system (I have up thru 8.2) and it hangs the package manager. Task Manager --> Kill Process Tree was the only way to get it to do anything beyond that point. I now suspect that the package manager (or openg) doesn't support versions of LabVIEW older than 6.0, but a nicer way of letting me know that would have been appreciated.
