Your example works well in my setting when I replace the usepackage by

\usepackage{Sweave}

which is on my file name database path of latex. Make sure you run "update file
name database".

\documentclass[a4paper]{article}
\usepackage{Sweave}
\begin{document}
\Sexpr{"Hello"}
\end{document}

to locate the problem more precisely.
