Dotfuscator command exited with code 1 xamarin.ios

I am trying to use PreEmptive Solutions - Dotfuscator with my Xamarin.IOS app, but the build fails and I am getting this error:

I have done all the steps from here:

https://www.preemptive.com/obfuscating-xamarin-with-dotfuscator

My Xamarin.Android works fine, but the IOS project fails.

The error:

The command ""C:\Program Files (x86)\Microsoft Visual Studio 14.0\PreEmptive Solutions\Dotfuscator and Analytics Community Edition\dotfuscatorCLI.exe" /p:InDir="obj\iPhone\Release\DotfuscatorXamarin\dfin",OutDir="obj\iPhone\Release\DotfuscatorXamarin\dfout",ReportDir="DotfuscatorReports\iPhone\Release" "DotfuscatorConfig.xml"" exited with code 1.

Any idea how I can fix it?
