Hi, here is the tool you are looking for: http://blogs.msdn.com/b/astebner/archive/2008/08/28/8904493.aspx download, unpack and run „ cleanup_tool.exe “ – from pull-down menu choose „.NET Framework “ what you want to uninstall and click „ Cleanup Now “. Maybe you can use the procedure that I wrote as the first response (points 1 to 11) of this thread (the page 1). LC

I tried to install it manually and it failed also

Hi LC - Thanks for the link and the suggested procedure. Would this work for Vista? It looks a bit tech-y for me but I may have a try tomorrow when I've more time. What's also puzzling me is that when I restart my PC and check for updates it now shows a message: "Windows is up to date", but all six problem updates are listed as Failed. Don't want to spend more time (and money) trying to sort out a non-problem. Andy

...x64 - is for 64bit WIndows 7

...x86 - is for 32bit WIndows 7

How to find out if Windows 7 is 32bit or 64bit is here:

EDIT 8/26/2011

Maybe what you can try (before you try points 1..11) only turn Off your antivirus and turn Off UAC, then manually install the updates that failed to installand run Windows update to install rest of updates. Turn On your antivirus and turn On UAC. How turn Off UAC see point 5).

EDIT 8/16/2011

If these steps above not help, try to use these ones:

1) uninstall Net Framework 4.0 client from „Uninstall and change program“:

2) If you still see Net Framework 4.0 client in „Uninstall and change program“ use this tool for unistallation Net Framework 4.0 client:
