IL2CPP compile error after upgrading 2018.2.0f2.

hello guys,
we met a IL2CPP error when upgrading unity2018.2.0f2 in android. it's ok in ios. anybody can help?
by the way, if we switch to Mono, it' ok.
Exception: C:\Program Files\Unity\Editor\Data\il2cpp/build/UnityLinker.exe did not run properly!

we fixed it by installing .Net FrameWork 4.6, before the pc only installed 4.5.

 

Here's the error, followed by the second error that pops up.
