    On servers with ASP.net 4.0, is ASP.net 3.5 also available. I have a forum installed as a sub-application, and it will only work with ASP.net 3.5. However, I'd like my parent application to use ASP.net 4.0.

    Hi,
    I don't see how that could be possible without stopping the site for each version.
    (Control panel)

    What is it about version 4 that's borking the other app?
    All the best,
    Mark

    This is not possible because each app pool can only run in 1 version of the runtime.

    Try upgrade your 3.5 app to 4.0
