JosephK Posted January 12, 2022 Report Share Posted January 12, 2022 (edited) Hello, I'm using JSON JKI's Flatten to JSON String.vi and Unflatten from JSON String.vi in a LabVIEW 2016 VI which I created, and I downloaded JKI JSON from here and installed it via JKI VIPM. However, I'm unable to run the program for the following reason: When I first open my VI in LabVIEW, LabVIEW cannot find the classes and VI's below: JKI Serialization.lvlib:Serializer.lvclass JKI Serialization.lvlib:Deserializer.lvclass JKI Unicode.lvlib:UTF-8 String.lvclass JKI Unicode.lvlib:UTF-8 String.lvclass:Index Rune as UTF-8 Substring.vi JKI Unicode.lvlib:UTF-8 String.lvclass:String Subset.vi JKI Unicode.lvlib:UTF-8 String.lvclass:String Length in Bytes.vi JKI Unicode.lvlib:UTF-8 String.lvclass:Create UTF-8 String.vi After ignoring these file searches, LabVIEW presents the following error window, which suggests that I don't have OpenG even though I've downloaded the latest version of OpenG from this NI website, and installed it via JKI VIPM. Additionally, according to JKI VIPM there are no missing dependencies for OpenG and JKI JSON as all the packages have been installed. I'd really appreciate any help with this matter, as I'm quite new to LabVIEW. Thank you. Edited January 12, 2022 by JosephK 1 Quote Link to comment Share on other sites More sharing options...
Jim Kring Posted January 12, 2022 Report Share Posted January 12, 2022 Hi @JosephK. Can you try opening VIPM and updating its package database by clicking the Refresh button? Then you should be able to find and install the missing JKI Serialization and JKI Unicode packages. Quote Link to comment Share on other sites More sharing options...
JosephK Posted January 12, 2022 Author Report Share Posted January 12, 2022 Hi @Jim Kring, When I click refresh the following message appears: Quote Link to comment Share on other sites More sharing options...
Jim Kring Posted January 12, 2022 Report Share Posted January 12, 2022 It looks like VIPM is not connecting to the Internet successfully. Can you look in the Settings and experiment with the proxy settings? Quote Link to comment Share on other sites More sharing options...
JosephK Posted January 13, 2022 Author Report Share Posted January 13, 2022 The issue has been resolved. For some reason clicking the Refresh button and right clicking individual packages listed under Name /\ did not reveal any missing dependencies in both Proxy configurations. However, what worked was to click View>Error List (or CTRL+L) and to install all the missing packages listed in the window that pops up. Thanks @Jim Kring for the quick responses, and for pointing me in the right direction to look for missing libraries! Quote Link to comment Share on other sites More sharing options...
Jim Kring Posted January 13, 2022 Report Share Posted January 13, 2022 OK, I'm glad you found a solution. I hope the JSON tool works well for you on your project. Quote Link to comment Share on other sites More sharing options...
