IL2CPP is not installed error

Unity Services
1

Our project compiles and works on the desktop.

When I use CloudBuild the WebGL version compiles correctly.

The Windows Desktop version produces the error (IL2CPP) is not installed error

1500: [Unity] ERROR: Error building Player: Currently selected scripting backend (IL2CPP) is not installed.
1501: [Unity] Error building Player: Currently selected scripting backend (IL2CPP) is not installed.
1502: [Unity] Finished exporting player successfully.
1503: ! build of ‘default-windows-desktop-64-bit’ failed. ! build failed - export directory is empty!
1504: publishing finished successfully.
1505: Finished: FAILURE

Before we moved to 2018.3 the desktop version compiled correctly.

Check the “Scripting Backend” option in the Player Settings for the Desktop Standalone Player. For standalone players, you can choose IL2CPP or Mono. It sounds like that option is set to IL2CPP, but the Unity installation is missing the IL2CPP for desktop standalone player package.

That “Unity installation”, is your installation in the cloud building service. One would expect all options would be available.

Oh, I’m not sure how I missed that this was cloud build, sorry. I believe IL2CPP is available in cloud build, but I’m not certain, so I’ll let someone from cloud build answer.

I’ve jumped around to a few posts here looking for answers on this. In many of them, I just see the conversation stop at a certain point like above. @JoshPeterson can you help get an update to this in any of the threads mentioning it?

I don’t know any more details about these issues, sorry. Are you seeing this in Cloud Build only, or does it happen locally as well?

It is Oct 30th today, I still face the problem on my Unity 2018.3.2f1, Is there anyway that I can install the single IL2CPP component without reinstalling the whole Unity Application?

No, you must install the full Unity to get an updated IL2CPP.

I get this in cloud build even today. 2019.3.4. Really annoying.

Up with this one…why is there still no support?

Cloud build doesn’t support IL2CPP builds for the Windows platform yet am i correct? Why isn’t this being advertised anywhere? I got teams advanced for this but i can’t use it so it seems.

We now have the ability to try out building Windows Standalone with IL2CPP. We’re looking for anyone interested in trying out out: Survey - Windows builders [ no longer accepting new applicants ]
