Unable to Update/Repair/Remove .Net Framework 4.5 Error Code 66A

[snowboi]

hi, i am having an issue with updating the .Net Framework 4.5 from Windows Update. It gets an error code "Code 66A". So i decided to use the Setup file to repair or remove it from my computer and then reinstall again but then there are errors too. "fatel error during installation". ive installed SURT and also did the sfc scan but was still unable to update. The update file number is KB2833957. I've attached all the logs and files i think that can help.

The CBS.log is incomplete - please reboot, and post a new copy

 

[snowboi]

alright. i have rebooted and attached the CBS.log again.

 

[NoelDP]

CBS.log and CheckSUR.log files are clear of errors.
I suggest downloading and running the .NET cleanup tool from .NET Framework Cleanup Tool User's Guide - Aaron Stebner's WebLog - Site Home - MSDN Blogs and then reinstalling .NET 4.5

i used the programme to remove the .net framework and reinstalled but then my computer auto shut down before the installation is complete. and then after i start to get blue screens.

Sounds like you may have other problems

Boot to Safe Mode, and see if that's stable - if it is, try using a Clean Boot to get into Normal Mode....

Ive successfully installed .net framwork but then i have a new problem, i cant update from windows update any .et framwork related updates. it either gives me a bluescreen or an error code 80072f78.

Try this....

This could be due to corruption in the SoftwareDistribution folder - the problem with that the conventional cure can lead to problems later on, if not handled properly, and you will lose your Update history (but the updates will still be installed, and viewable in the Installed Updates listing).

Open an Elevated Command Prompt
Run the following commands

NET STOP WUAUSERV
REN C:\WINDOWS\SoftwareDistribution SDOLD
NET START WUAUSERV

wait 15 minutes, and reboot
then wait 10 minutes, and open Windows Updates, and run a Check for Updates.

Install only the oldest update found - and reboot once installed
then go back to Windows updates and install the others.

 

[snowboi]

its still not working. it downloaded the update, but cant install it. still the same, auto shut down and blue screen.

 

[NoelDP]

Please open Event Viewer
In the left pane, navigate to the Windows Logs
right-click on Applications and select 'Save all events as...' save as Apps.evtx
repeat for the System logs - save as Sys.evtx
Compress both files, and attach to your reply.

 

[snowboi]

here are the files you requested.

 

[NoelDP]

There are a lot of errors there!

Please run the following command in an Elevated Command Prompt....

regsvr32 %windir%\system32\rsaenh.dll
ICACLS C:\ProgramData\Microsoft\Crypto\RSA
netsh p2p pnrp cloud show names
netsh p2p pnrp peer resolve 0.testingpnrp


post the results

Here are some instructions to make life easier
1) To open an Elevated Command Prompt Window (the ECP window), click on Start, All Programs, Accessories – then right-click on Command Prompt, and select Run as Administrator. Accept the UAC prompt.
2) To run the commands easier, highlight the block of commands, and right-click on the highlight – select Copy. In the CP Window, click on the black/white icon at top left – select Paste. The commands will run but may not complete the last command, so hit the Enter Key once.
3) To copy the results... click on the Black/White icon in the top left, and select Edit... 'Select All', and hit the Enter key - then use Ctrl+V or r-click+Paste to paste it into your response.

You could try a repair install

[NoelDP]

Open an Elevated Command Prompt, and run the following command

NETSH WINSOCK RESET

reboot on request, then run the following commands again

ICACLS C:\ProgramData\Microsoft\Crypto\RSA
netsh p2p pnrp cloud show names

 

[snowboi]

Please run the following command

REG QUERY HKLM\SYSTEM\CurrentControlSet\services\WinSock2 /S >>%userprofile%\desktop\winsock2.txt

It will place the file winsock2.txt on your desktop - please attach that to your reply.

 

[NoelDP]

I wish I knew which 'underlying system' it was talking about!

I'm asking for assistance - don't run away

 

[snowboi]

here's the winsock2.txt file!

This may be your "underlying system"

This error is returned by WSAStartup if the Windows Sockets implementation cannot function at this time because the underlying system it uses to provide network services is currently unavailable. Users should check:

that the WINSOCK.DLL file is in the current path,
that the WINSOCK.DLL file is from the same vendor as the underlying protocol stack. They cannot be mixed and matched (WinSock DLLs must be supplied by the same vendor that provided the underlying protocol stack).
that they are not trying to use more than one Windows Sockets implementation simultaneously. If there is more than one WINSOCK DLL on your system, be sure the first one in the path is appropriate for the network subsystem currently loaded.
the Windows Sockets implementation documentation to be sure all necessary components are currently installed and configured correctly.
