Hi! I am not sure if this is the correct place to post this, but I have scoured the internet and all of the different forum post related to this. Please have some patience, because part of the problem is that I lack the technical skills to completely understand how to debug the issue and follow the instructions given. I have also inherited the code base, so there might be aspects of the code that causes issues, but I cant see them intuitively.
The issue is that when building for android using il2cpp, the build fails with the following error message: System.ComponentModel.Win32Exception: The specified executable is not a valid application for this OS platform
(Including full output at the end of the post)
I am trying to build with Unity 2019.1.10 and 2019.1.11f - I can on request try to build on a newer version of Unity, but last time i managed to complete a build was on the 2019.1.10f version, so I have reverted the project to that state to see if i could manage to make a build at all.
Some of the things that i have investigated:
I tried to make a build using mono, mono worked.
I have tried to see if the is an issue with NDK install location - I have met a blocker here, because I do not know how to check this. What i have done is install android build support through Unity hub (for unity 2019.1.10f). And also through the in editor prompt when trying to switch to a target platform that you lack the build tools for (using unity 2019.1.11f). In the latter case, Hub does not mark the Unity version as having the android module installed
I am running windows 10.
I am unable to share a complete copy of the project.
output:
