original title: Cannot update to .NET framework 3.5 SP1 and family update KB951847

I am unable to install this update- Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update (KB951847) x86


Every time I do, the installation runs fine, it asks to restart in order to change system files and I click restart. It configures update, restarts again, configures some more, then reverts changes then tries again then reverts changes till I finally reach my desktop.

In problem reports and solutions, there are several problems by windows modules installer such as "WindowsWcpOtherFailure3", "WindowsWcpAIFailure3" and "CbsPackageServicingFailure".

I have tried the following - used the dot netfx cleanup tool, closed all running programs and antivirus while installing, removed any trace of .net framework in installed updates and installed programs, tried to install it again but no luck.

Now it shows up as failed in update history and windows update still asks for it, but I can see this in installed updates - 
Hotfix for Microsoft .NET framework 3.5 SP1 (KB953595)
Hotfix for Microsoft .NET framework 3.5 SP1 (KB958484)

This issue can be caused by a damaged .NET Framework component. In order to resolve the issue, we have to remove previous versions of .NET Framework and reinstall .NET Framework 3.5, which contains many new features building incrementally upon .NET Framework 2.0 and 3.0, and includes .NET Framework 2.0 service pack 1 and .NET Framework 3.0 service pack 1. Based on its current status, I suggest trying the following troubleshooting steps.
