Can't make an APK without the compiled .so (From launcher)

When I try to launch my android game with the launcher, it stop and the error is:

Program.Main: ERROR: AutomationTool terminated with exception: ERROR: Can’t make an APK without the compiled .so [C:\Users\Simon\Documents\Unreal Projects\VR\Binaries\Android\VR-armv7-es2.so]

I am using UE 4.14 downloaded from the Epic launcher, not from source code. I’m using SDK24 and ARMV7.
Support x86 is uncheck.
Thanks for the help!
