Error Message Concerning Plato C++

Dear Silverfrost Community: I am running the most recent edition of the Plato IDE with a 64 bit Windows operating system. When I attempt to implement a program written for the C++ component of the Plato IDE, I get the error message: 'Plato cannot process C++ files for .NET' What does this error message mean, and how can I fix the situation so I can run programs using the Plato IDE? Thank you.

You should select Win32 (Checkmate or Debug or Release) on the main toolbar.

Silverfrost does not provide a C++ compiler for .NET, only for Win32 and (in a limited and unsupported way for) x64.
