(another) cannot download update KB2478663 for Microsoft.NET 4

Hello all. I've had to disable automatic updates as this one and KB2518870 don't install and the PC keeps trying to download them every day! When I go into control panel it tells me that I have MS.NET Framework 4 Client Profile. But cannot uninstall it. When I go to the "turn windows feature on/off" option it says I have MS.NET Framework 3.5.1

I've tried reloading version 4 from the MS website but it tells me I already have version 4 (or the download is being blocked). I've tried a clean boot - doesn't help. I've tried turning off Norton - doesn't help. Error code is 66A (unknown error).

I'm running Windows 7 Home premium on a Dell Studio One. Problems with these downloads seem to be quite common.

I've tried downloading them individually - doesn't help.

All fixed. First the 2 updates disappeared from the important list without being installed and a MS.NET Framework 4 Client Profile update appeared in the recommended list. After installing this the other 2 reappeared in the important list and installed without any problem! It's a mystery to me.

Good to note that all is now well.
