For the last five hours I've been trying to install Microsoft SQL Server 2008, first on Windows 7 and then Windows XP. Both have had the same issue. Even before the installation starts, an error message appears saying:
Microsoft .NET Framework 3.5 SP1 installation has failed. SQL Server 2008 Setup requires .NET Framework 3.5 SP1 to be installed.
I have installed everything in the hope of getting past this. the service pack it refers to has even been installed and I can see them in the control panel!
I have installed Framework 2.0, Framework 2.0 SP1, Framework 3.5, Framework 3.5 SP1, Windows Installer 3.5 and Windows Installer 4.0. Even installed the Service Pack for SQL Server 2008.... But, nothing, works!
Does anyone have an idea what I'm doing wrong or what could be wrong? I'm seriously close to the end of my tether, I've even sent Steve Ballmer an email with my frustration. I would seriously appreciate some help with this.
