Error building Player error after adding Metro Ads plugin

Hi,
I've just imported the Metro Ads plugin from prime 31. In end of the build process I get this error message:

Error building Player: Exception: Failed to run Reference Rewriter with cmdline --target="Temp/StagingArea\P31MetroAds.dll" --framework="C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETCore\v4.5.1" --platform="C:\Program Files (x86)\Windows Kits\8.1\References\CommonConfiguration\Neutral\Windows.winmd" --support="Temp/StagingArea\WinRTLegacy.dll" --system=System --dbg=pdb --alt=System.Xml.Serialization --ignore=System.IConvertible,mscorlib.[Temp/StagingArea\P31MetroAds.dll]

I read the official plugin documentation at Prime31's web site and it says:

"Important: if you are using Unity 4.5.1 or newer you have to make a modification to the Windows Store Player Settings. Open the "Publishing Settings" tab and add "P31MetroAds.dll" to the list of "Unprocessed Plugins".This will ensure Unity's DLL processor doesn't mess with the DLL and cause build errors."

but I cant find where to add the dll in the Publish Settings. Is there another way to fix it?

 

I found it but when I expand Publish Settings there is only one Size field and its value is "0". I tried to change it but when I select something else it turns back to "0".

PS : I use Unity 4.5.2f1

 

Same problem here, with 4.6.3f1. is there any solution for this !!

 

Hi,
Aurimas Cernius
It was confusing what to do there, finally i past just "P31MetroAds.dll" there. It works fine.
Thanks.
