I guess it should be "C:\\PDF_Solution.doc" instead of "C:\PDF_Solution.doc".
If it was a typo and corrected code doesn't work anyway then try the following:

QDesktopServices::openUrl( QUrl::fromLocalFile( QDir::fromNativeSeparators( "C:\\PDF_Solution.doc" ) ) );

QDesktopServices::openUrl( QUrl::fromLocalFile( QDir::fromNativeSeparators( "C:\\PDF_Solution.doc" ) ) );

"C:\\PDF_Solution.doc" is not a Windows executable file. The Windows API CreateProcess call that Qt ultimately uses expects an executable. The file type association magic you are expecting to happen is managed by the Windows shell (and by extension by QDesktopServices).
