Framework 3.5 SP1 will not load on Windows 7 RRS feed

  • Question

  • I really need to upgrade from SQLSERVER 2005 Express to 2008 Express.   However, when I try to install, it tells me I must apply SP1 to Framework 3.5.    I have tried everything I could find in the documentation including removing Framework 2.0.   I downloaded the Windows Uninstaller program intending to just uninstall Framework 3.5, but it appears it uninstalls 50 - 60 programs if you run it.   What is so frustrating is that when I try to run the SP1 for Framework 3.5, it never gives a single message but just immediately drops back to the window from which I selected it.   I have tried  RUN AS ADMINISTRATOR with the same results.   I turned on the error logging in the WINDOWS INSTALLER in the registry, but I can not find any MSI*.log file to review for help.    Can anyone give me some guidance on this?

    I have Visual Studio 2008 loaded and desire to get the Microsoft Web Developer loaded (which requires sql2008) and I am stuck on getting SP1 installed on the framework 3.5 before I can proceed to the next step.   I should also mention that I need 64 bit version, and I only find one sp1 for Framework 3.5 (dotnetfx35setup.exe).

    Thanks,

  • Hi David,

    Thank you for your post.

    For Windows 7, it includes the .NET Framework 3.5.1 as an OS component. This means you will get the .NET Framework 2.0 SP2, 3.0 SP2 and 3.5 SP1 plus a few post 3.5 SP1 bug fixes. The feature of 3.0 SP2 and 3.5 SP1 can be added or removed via the Programs and Features control panel. Thus, we don't need to manually download .NET Framework 3.5 SP1 and install it on Windows 7. That's why your OS will not let you install it.

    For you concern, could you please try this Verification Tool to verify .NET Framework 2.0 SP2, 3.0 SP2 and 3.5 SP1 on your machine?
    Please check "Current status" to know the result of verification - success or failed.
    If they fail to be verified, we need to repair them. If you need to repair the .NET Framework 3.5.1 on Windows 7, you will need to use instructions like the ones in this blog post. (Also applied for Windows 7)

    Hope this helps. If you have any concern, please feel free to let me know.

    Best regards,
    Yichun Chen
