**Original Discord Post by sirpwnage | 2023-11-28 20:48:07** Hi all I am taking a project I have been working on in Unity 2021.3.4 Visual Studio 2019 16.11.20 MRTK 2.8.3.0 I have had many successful builds till adding convai, so I was curious if anyone else has been able to build to a UWP platform with unity with success and what versions you may have used? I am going to update the project and packages to newer versions to see if that will help my build issues. Attached are the errors I get in visual studio when trying to build now. I will update as I go cuz I also am working on a script to detect an air tap to toggle NPC StartListening() and StopListening() **Attachments:** - [message.txt](https://cdn.discordapp.com/attachments/1179161826257276988/1179161826378924153/message.txt?ex=673e4b07&is=673cf987&hm=3507140f851ccf1664c291b7e061288d4c23e841697228cacb305f38d23f0d39&) ---

**Reply by sirpwnage | 2023-11-28 20:52:09** I’ll clarify for Hololens2 the build must be in .Net Framework and ARM64-bit and visual studio must also build in ARM64 for the Hololens2 to run the build ---
