Hi @JKI-OfAllTrades,
Looking at the VI Peek package info, I see that it's compatible with LabVIEW 2020 or greater, which is why it's not showing in your package list.
Note: In the VIPM Settings window you can show all packages, even if incompatible with the selected LabVIEW version. However, you won't be able to install it.
One idea is to download the source code and then use LabVIEW 2020 Community Edition to Save For Previous into LV2017.
Good luck!
