Some applications contain native code which is optimized for a certain CPU architecture (generally, there are two of them: 32-bit armeabi-v7a and 64-bit arm64-v8a).
You can add two APKs for one application, see details here:

Also, you can consider updating Headwind MDM. In latest versions, this is not an error causing failure to install, but just a warning, so you can use one native-code APK on both CPU architectures.
