Hello Natassa kar,

Method 1:

There are a few things that could be causing this issue, please try these steps first,

1. Open Administrative Tools by clicking the Start button, clicking Control Panel,and then clicking Administrative Tools.

2. Double-click Services. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

3. Right-click the Windows Update service, and then click Stop.

4. Click start, then click all programs, then click accessories, then right click command prompt and choose to run as administrator.

Type:
net stop wuauserv
regsvr32 wuapi.dll /s
regsvr32 wuaueng.dll /s
regsvr32 wucltux.dll /s
regsvr32 wudriver.dll /s
regsvr32 wups2.dll /s
regsvr32 wups.dll /s
regsvr32 wuwebv.dll /s
net start wuauserv
exit

Restart the system and see if it can update now.
If this does not fix the problem you could also try repairing the BITS service, by following the below article:

Method 2:

Download the .Net Framework removal tools "dotnetfx_cleanup_tool.zip" from the below link,
http://blogs.msdn.com/astebner/attachment/8904493.ashx

Run the tool & you should remove only that version for which you are receiving error code. (i.e. you should only remove .NET Framework 3.5 & its service packs package)

Then, restart your computer & manually install the following updates in order
1) Microsoft .NET Framework 3.5 package from the below link:
http://www.microsoft.com/downloads/details.aspx?FamilyId=333325FD-AE52-4E35-B531-508D977D32A6&displaylang=en

2) Microsoft .NET Framework 3.5 Service Pack 1 from the below link:
http://www.microsoft.com/downloads/details.aspx?familyid=ab99342f-5d1a-413d-8319-81da479ab0d7&displaylang=en

3) Now, download & install .NET Framework 3.5 Family Update (KB951847) x64

Hope this helps.
