command returned 1

If /C or /K is specified, then the remainder of the command line after
the switch is processed as a command line, where the following logic is
used to process quote (") characters:

 1.  If all of the following conditions are met, then quote characters
     on the command line are preserved:

     - no /S switch
     - exactly two quote characters
     - no special characters between the two quote characters,
       where special is one of: &<>()@^|
     - there are one or more whitespace characters between the
       two quote characters
     - the string between the two quote characters is the name
       of an executable file.

 2.  Otherwise, old behavior is to see if the first character is
     a quote character and if so, strip the leading character and
     remove the last quote character on the command line, preserving
     any text after the last quote character.
