This sound like an installation issue. Win32::ODBC is a old method of using ODBC connections under perl. This is about 5 years old and predates Windows 2000 by some margin.

I would recommend DBI and DBD::ODBC driver to generate more maintainable and portable code unless there is a particular reason for using Win32::ODBC (eg. legacy code). If you require multiple datasets from SQL Server which Win32::ODBC supported have a look at DBD::FreeTDS.

Hope it helps
