Hello Natassa kar,
Method 1:
There are a few things that could be causing this issue, please try these steps first,
- Open Administrative Tools by clicking the Start button, clicking Control Panel,and then clicking Administrative Tools.
- Double-click Services. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
- Right-click the Windows Update service, and then click Stop.
- Click start, then click all programs, then click accessories, then right click command prompt and choose to run as administrator.
Type:
net stop wuauservregsvr32 wuapi.dll /sregsvr32 wuaueng.dll /sregsvr32 wucltux.dll /sregsvr32 wudriver.dll /sregsvr32 wups2.dll /sregsvr32 wups.dll /sregsvr32 wuwebv.dll /snet start wuauservexit
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:

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
- Microsoft .NET Framework 3.5 package from the below link:
- Microsoft .NET Framework 3.5 Service Pack 1 from the below link:
- Now, download & install .NET Framework 3.5 Family Update (KB951847) x64
Hope this helps.
