Security Update for Microsoft .NET Framework 4 (KB2446708) keeps installing again and again.

I've done it twelve times now (all 12 shown in "update history"), re-booted several times between download/installs but Windows Update keeps bringing it back up as being an important update requiring installation. It's sitting there now as available in Windows Update.

 

What's wrong? Is it not installing fully maybe? (It shows up once in "installed updates" so I don't think that can be the problem.)

 

Not sure if it's relevant but I upgraded from Vista Home Premium to 7 Home Premium the day before yesterday and it all went without a single real glitch. This minor problem is the only thing that's not gone all that smoothly, which is quite impressive in itself 'coz I was nervous of upgrading without doing a clean install. If this is the only problem I get, I'll be a happy bunny (and I don't think this is particularly related to the upgrade anyway).

 Hi there: I had exact same problem...What to do is download dotnetfx_cleanup_tool.zip from here..  http://cid-27e6a35d1a492af7.skydrive.live.com/self.aspx/Blog_Tools/dotnetfx_cleanup_tool.zip       Unzip files and run tool and select to remove .NET Framework 4 (there is a drop window asking which .NET Framework you wish to remove,make sure you select .NET Framework 4.)..This tool will safely remove client profile part of .NET Framework 4. You will not be able to remove it by using add/remove programmes as normal because it has become corrupt.Once tool has removed files restart computer and check windows update.You should find .NET Framework 4  client profile offered as an update (KB982670).Download and install this..Restart computer again and run windows update.You should be offered the problem KB2446708 as a high priority update.Install this and it should be fine, you shouldn't see it reappear again as before. Best of luck.
