TS2025 Q2 Not finding .NET System.dll

[KevRotork]

Hi, 

I have created a simple LabVIEW Project.

Test 1 - Fault.vi 

Test 2 - Blank

Is just an empty VI

I am creating a Packed Library

I am then planning to call this in TestStand using a LabVIEW Action Step, I am getting the following error

I am using TS 2025 Q2 and LV 2025 Q1 Win 11

This was working on my previous setup of LV 2023 Q1 TS 2022 Q4 

Looking at the Log located here: C:\Users\<USERNAME>\AppData\Local\Temp\TestStand

Its suggesting the VI is broken.

But it isn't. Even if I call the ppl from another LabVIEW project the VI is fine.

Only when called in TestStand

Please help - What am I missing
