[Hololens] ERROR: No required compiler toolchain found (Hololens 2 emulator)

[anonymous_user_1fae6113]

I am trying to package a model in UE4 for the Hololens 2 emulator but receive this error message UATHelper: Packaging (HoloLens): ERROR: No required compiler toolchain found in C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.23.28105. I have Visual Studio installed. Any help appreciated

You need UWP development with C++ UWP tools

indeed BuildTools for UWP were the one which my system missed. I could install it through Apps&features/VS2019 and then search for it directly under induvidual components of the Microsoft VS-Installer.

Hello,

I am also experiencing this issue when building for HoloLens on Unreal Engine 4.25.1.

UATHelper: Packaging (HoloLens):   ERROR: No required compiler toolchain found in C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.26.28801

However I already have UWP installed and the folder “C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.26.28801” exists.

Has anyone else experienced/resolved this issue?

You need MSVC v142-VS 2019 C++ ARM64 Build Tools(v14.26)

Hello all,

I have this exact problem, and double checked that MSVC v142-VS 2019 C++ ARM64 Build Tools(v14.26) was installed. Any news about the issue?

Edit: publishing for emulator works but not for a Hololens app

You need the following

[SourceSoft]

dont download all sections in UWP it will take space just make sure to download the C++142, USB Device Connectivity, Window sdk 10.0.19041 and dont Forget Window sdk10.0.22621 this sdk is for Window11 but it is also important for Window 10 i dont know why if you dont download this you cant able to generate Sign Certificate in Project setting.

Peace
