SQL Server 2008 Installation issue in Windows 7 64 bit

    Question

  • I'm trying to install SQL 2008, but an error message keeps appearing:

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

     

    My OS is Windows 7 Ultimate 64 bits, so already has de .NET Framework 3.5, I turned on/off a lot of times and the same error occurs!

    I download the .NET Framework 3.5 and .NET Framework 3.5 SP1 from the links:

    (http://www.microsoft.com/downloads/details.aspx?FamilyId=333325fd-ae52-4e35-b531-508d977d32a6&displaylang=en

    http://www.microsoft.com/downloads/details.aspx?familyid=AB99342F-5D1A-413D-8319-81DA479AB0D7&displaylang=en)


    But, when installing the Framework 3.5 or the SP1, I get the message: "Use turn on or off disable features in Windows control panel".

     

    Someone can help me?!

    - Windows 7 Ultimate 64 bits

    - SQL Server 2008 Developer (x86, x64, ia64).

     

    Thanks!

  • Did you try running the setup using "Run as Administrator" ?

    Sure!

    1. In Control Panel , Programs , Click Turn Windows Features on or off and turn off the Microsoft .Net Framework 3.5.1

    2. Unistall the SQL Server 2008.

    3. Delete the remaing folders, usually in C:\Program Files\Microsoft SQL Server\ and C:\Program Files (x86)\Microsoft SQL Server \

    4. Clean the registry. 

          4.1. You can do this manually: Start , Run , type regedit and delete the registry from SQL Server, usually in HKEY_CURRENT_USER\Software\Microsoft\Microsoft SQL Server and HKEY_LOCAL_MACHINE\SOFTWARE\ Microsoft\Microsoft SQL Server.

          4.2 . Or, you can use some software to clean the registry, such as CCleaner - www.piriform.com ( Highly recommended).

    5. Install the Windows Installer 4.5 (http://www.microsoft.com/downloads/details.aspx?FamilyID=5a58b56f-60b6-4412-95b9-54d056d6f9f4&displaylang=en)

    6. Back in Control Panel , turn on the Microsoft .Net Framework 3.5.1

    7. Install the SQL Server 2008

    8. Use Windows Update to download the SQL Server 2008 Service Pack 1.

     

    Hope it help!
