Error with T4 template running it by command line

Error with T4 template running it by command line

I'm trying to execute the "Run custom tool" action from command line. In
this way:
C:\Program Files (x86)\Common Files\microsoft
shared\TextTemplating\10.0>TextTransform.exe "C:\Carlos\Automatic Unit
Testing\Examples\T4Example\T4Project\T4Project\MultipleOutputFiles.tt"
When executing that, i'm getting this error:

Aditionally, when hitting the option "Debug T4 template", I get this message:
There was a problem getting an AppDomain to run the transformation from
the host. The process cannot continue.
I hope all this information helps you understand my issue.
I'll wait your asnwers :)
Thank you,
