.NET 8 SDK required to load .NET 8 DLL

[soundslikesound]

Hello, I decided to use company internal DLL built in .NET 8 in my Labview app. I built new installer which include Labview 2026 Q1 64-bit runtime and .NET 8 Desktop Runtime (both 32-bit and 64-bit). However on production PC Labview executable on launch throws error "Labview (Hex 0x6f6) a runtime error occurred while executing the .NET Core code. The file 'Sapper.dll' could not be loaded.". Sapper.dll is internal library.  

Printscreen from NI Package Manager

This issue fixed installing .NET 8 SDK on production PC. Why is SDK needed for loading library?
