Update for .NET Framework 3.0: x86 (KB932471) failed to install

After I installed .NET Framework 3.5 and checked in Windows Update, I saw
there was one optional update: Update for .NET Framework 3.0: x86 (KB932471),
which failed to install. I downloaded the update manually and found out the
problem was the update is supposed to be applied on .net framework 3.0, but
not 3.0 SP1 contained in .net framework 3.5.
Looking deeper into the problem, I also found from the KB article of the
update that it only updates one file:
C:\WINDOWS\system32\XPSViewer\XPSViewerManifest.xm l. However, the date the KB
article provides is older than that of the file after installing .net
framework 3.5. Consequently it can be justified that the update is actually a
false positive, and since the new file is newer than what is contained in the
KB update (of the same size), there is actually no need to apply the update.

Same here. But my problem is slightly different. Cannot install it anyway
and I don't understand why. Iget an error message and that's it! Nothing
else
