I cannot install framework 3.5 sp1 on my pc


  • Although I have used computers for years, I am not a programmer.  It is obvious to me that I need the "for dummies" step by step instructions in order to execute the changes as suggested by earlier contributors.  Can anyone help me.

  • Hi Gscottrell,


    Welcome to the MSDN forum.


    Could you please let me know what you want is a guide about installing .NET Framework 3.5 SP1?

    What is your OS and Service Pack level?


    For Windows 7 and Windows Server 2008 R2, .NET Framework 2.0 SP2, .NET Framework 3.0 SP2 and .NET Framework 3.5 SP1 are embedded in OS, so you are not required to install it.


    First, you can download full version of .NET Framework 3.5 SP1 here:


    Before you begin to install it, please clean up %temp% folder and complete all Windows updates. Make sure all antivirus and antispyware are turned off during the installation. Also, run it as administrator.


    If you encounter any error during the installation, please use this tool to collect the logs:

    After you run it, you can upload located in %temp% folder to an open website or send it to me (v-alsun_at_microsoft_dot_com).


    If you have any other concerns, please feel free to let me know.


    Best Regards,
