// SQL Server Express is supported on x64 and EMT64 systems in Windows On Windows (WOW). SQL Server Express is not supported on IA64 systems
// requires Microsoft .NET Framework 2.0 or later
// SQLEXPR32.EXE is a smaller package that can be used to install SQL Server Express on 32-bit operating systems only. The larger SQLEXPR.EXE package supports installing onto both 32-bit and 64-bit (WOW install) operating systems. There is no other difference between these packages.
