    Hi, have been experiencing similar for ages but unable to repair .NET Framework 4.

    1. Only options I get is uninstall/change
    2. Tried 'change' but before I could do anything received a 'pop up' "setup encountered an unexpected error in the package contents. The package will not be installed. Please contact your vendor for a new package."

    ... Help!    8-)
