• I have a new server onto which I have installed Windows Server 2008 R2 Enterprise. I have not been successful at installing SQL Server 2008 Enterprise on it. After many attempts, I continue to get the following error message:

          Microsoft .NET Framework 3.5 installation has failed.
          SQL Server 2008 setup requires .NET Framework 3.5 to be installed.

  Some notes:

  • I got my copies of Windows Server 2008 R2 and SQL Server 2008 Enterprise through my MSDN subscription.

  • Upon first installing WinServer2008 R2, I notice that the .NET Framework 3.5.1 is not installed and is not available as a feature to add through the Programs and Features control panel.

  • Upon first installing WinServer2008 R2, Server Manager does not list .NET Framework 3.5.1 as a feature to add in the Add Features Wizard. What is listed, however, is: “.NET Framework 3.0 Features”.

  • After adding the Framework 3.0 feature through Server Manager, the .NET Framework Setup Verification Tool lists 2 entries available for verification… Framework 2.0 and Framework 3.0.

  • Upon first installing WinServer2008 R2, neither “v3.0” nor “v3.5” is listed in the registry key “HKEY_LOCAL_MACHINESOFTWAREMicrosoft.NETFramework” but “v2.0.50727” is listed.

  • After installing .NET Framework 3.5 SP1, “v3.0” and “v3.0 SP1” now appear in this key.

  • Upon first installing WinServer2008 R2, neither “v3.0” nor “v3.5” is listed in the registry key “HKEY_LOCAL_MACHINESOFTWAREMicrosoftNET Framework SetupNDP” but “v2.0.50727” is listed.

  • After installing .NET Framework 3.5 SP1, “v3.0” and “v3.5” now appear in this key.

  
  Upon starting the SQL Server setup, it checks for pre-reqs and says it requires .NET Framework and an updated Windows Installer to be installed. Upon clicking OK, it starts the pre-req setup process and immediately fails while attempting to install .NET Framework 3.5 SP1… thus my error message above.

  Searching the net, I found some suggestions, but none have worked to enable 3.5.1 to appear installed and available… and none have worked to get SQL Server setup to run. I have tried the following:

  •  tried re-installing WinServer 2008 R2 numerous times thinking perhaps something was missed during the setup process. Nothing new installed.

  • installed .NET Framework 3.5 Service Pack 1. After completion, still no “3.5.1” appears as an available feature to add in Server Manager. In Programs and Features control panel, “Microsoft .NET Framework 3.5” does appear as an installed feature, available for Unistall/Change.

  • After installing .NET Framework 3.5 Service Pack 1, I run the .NET Framework Setup Verification Tool and find 3 entries available for verification… Framework 2.0, Framework 3.0 and Framework 3.5… but no Framework 3.5.1. The log from this tool says that 3.5 service pack 1 (Framework v3.5.1) is not installed.

  • The update does not apply to your system

  • The update does not apply to your system

  • None of the products that are addressed by this software update are installed on this computer. Click Cancel to exit setup.

  •  tried installing SQL Server 2008 Service Pack 1 to get the pre-reqs installed… then install SQL Server… and then the service pack again afterwards. This approach fails with the following message:

  • SQL Server 2008 Setup requires Microsoft .NET Framework 2.0 SP2 to be installed.

  I thought that .NET Framework 2.0 was already installed with WinServer 2008 R2.

  These approaches included numerous reboots scattered within. I’ve read accounts of 3.5.1 appearing as the feature to addd via Server Manager. Any ideas on getting Framework 3.5.1 available on my machine would be appreciated. Thanks.

• Question

• Today (8/14/2008) I downloaded SQL Server 2008 Express (SQLEXPR32_x86_ENU.exe).

  When I attempt to install it I get the following message:

  SQL Server 2008 Setup requires Microsoft .NET Framework 2.0 SP2 to be installed.

  Microsoft .NET Framework 3.5 is currently installed.

  Do I really have to use .NET 2.0 SP2?

  I’m attempting to learn C# using Microsoft Visual C# Step by Step book.

  Thanks for any help.

• Hi experts,

  I intend to redistribute SQL Server 2008 Express R2 in my installer. I’ve extracted the setup files from SQLEXPR32_x86.exe and pass in the appropriate command line parameters during the setup.

  Recently, I noticed if I applied the following Windows Update: .NET 4.0 Client Profile, I will hit into the following error when I installed SQL express.

  .NET Runtime 4.0 Error Reporting

  EventType clr20r3, P1 setup100.exe, P2 10.50.1600.1, P3 4bb67524, P4 mscorlib, P5 4.0.0.0, P6 4ba1da6f, P7 44f0, P8 32, P9 system.security.security, P10 NIL.

  .NET Runtime

  Application: setup100.exe

  Framework Version: v4.0.30319

  Description: The process was terminated due to an unhandled exception.

  Exception Info: System.Security.SecurityException

  Stack:

  at Microsoft.SqlServer.Chainer.Setup.Setup.DebugBreak()

  at Microsoft.SqlServer.Chainer.Setup.Setup.Main()

  Running the setup.exe from a file server will give these errors but if I copied the entire setup files to a local folder and run setup.exe from there, it runs fine.

  May I know what am I missing? I definitely need to support to install SQL express running from a file server location.

  Thanks,

  MK
