What do you have in your user-config.jam (if anything)? In Jam version, when you have no version 
specified, the following code in msvc.jam:configure-really is supposed to kick in:

     # Decide what the 'default' version is.
     if ! $(v)
     {
         # Take the first registered (i.e. auto-detected) version.
         version = [ $(.versions).all ] ;
         version = $(version[1]) ;
         v = $(version) ;

         # Note: 'version' can still be empty at this point if no versions have
         # been auto-detected.
         version ?= "default" ;
     }

Where .versions is created with:

        .versions = [ new configurations ] ;

at the top-level, and then populated with auto-discovered versions.
