Installing SQL Server 2003 With 2008 R2 Disk

Hey All,

I'm Working a project that the customer got me SQL Server to install on their Server. Only problem is, It's a Windows Server 2003 (32-bit, by my guess) and the Version of SQL they got is 2008 R2. I can't get past the .Net Framework install. Modifying the Server is Not an option, so what can I do to install SQL Server 2003 with a 2008 Disc and License?

Thanks,

Tony
