KB2742599 will not install. Error 800B0100

Error code 800B0100
I ran the SURT and it fails on this install too.
I ran the sfc scan and it didn't find anything.

I think this has something to do with WebRoot software that was previously installed. This is my mothers PC.
I ran the uninstaller and cleanup tool provided by webroot but some issue. The update fails

Windows 7 Home x64

Thanks.

Your earlier runs of CheckSUR appear to have completed properly, and fixed all found problems...
Code:
Summary:
Seconds executed: 3400
 Found 44 errors
 Fixed 44 errors
  CSI Manifest All Zeros Total count: 41
  Fixed: CSI Manifest All Zeros.  Total count: 41
  CBS MUM Corrupt Total count: 3
  Fixed: CBS MUM Corrupt.  Total count: 3
  Fixed: CBS Paired File.  Total count: 3
However, SFC is still complaining about problems which CheckSUR should be finding.
There are a large number of instances of this error...
Code:
Line 1386: 2014-01-25 10:35:42, Error                 CBS    Failed to verify if catalog file \\?\C:\Windows\SoftwareDistribution\Download\4e6ee18e9ad6abc3f0cc99df193373ca\update.cat is valid. [HRESULT = 0x800b0100 - TRUST_E_NOSIGNATURE]
 Line 1388: 2014-01-25 10:35:42, Error                 CBS    Failed to create internal package [HRESULT = 0x800b0100 - TRUST_E_NOSIGNATURE]
This implies that the SoftwareDistribution\Download folder is corrupted in some way.



Open an Elevated Command Prompt
Run the following commands

NET STOP WUAUSERV
REN C:\WINDOWS\SoftwareDistribution\Download download.old
NET START WUAUSERV

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.
