    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."

    You have got to uninstall your .NET Framework and do a clean re-install of above mentioned .NET Product........

    if can't uninstall your .NET using Normal Mode the boot your system using Safe Mode and then try uninstalling the .NET and see if it helps.......

    If not then use the .NET Framework uninstaller......

    after the clean-up do a clean install of .NET and see if it helps.......
