SQL Server 2008 R2 setup error on Windows Developer Preview

Question

I'm trying to install SQL Server 2008 R2(Express) on Windows Developer Preview (32bit) but getting a strange error:

---------------------------

Microsoft SQL Server 2008 R2 Setup

SQL Server 2008 R2 setup requires Microsoft .NET Framework and an updated Windows Installer to be installed.

To enable the .NET Framework Core role, click OK. To exit Setup, click Cancel.

OK Cancel

Even I clicked OK but the error comes again and again. Do you know the reason and the solution?

Answer 1

I just installed .NET framework 3.5 SP1 and it worked.
