Can I uninstall .NET 2 SP2 if I have 3.5 SP 1? RRS feed

  • Question

  • This page suggests to migrate .NET 2 SP 2 with 3.5 SP 1. Does that mean I can uninstall 2 once 3.5 is installed? Will apps made with 2 still work?

  • Hi homer_3,

    Welcome to MSDN forum.

    No, you cannot use the .NET Framework 3.5 SP1 unless you also have the .NET Framework 2.0 SP2 and 3.0 SP2 installed. Therefore, you will not be allowed to uninstall the .NET Framework 2.0 SP2 or 3.0 SP2 if you have the .NET Framework 3.5 SP1 installed. If you try to uninstall the .NET Framework 2.0 or 3.0 when the .NET Framework 3.5 is installed, their uninstall processes will block and tell you that they are needed by another application on your system.
