Failing to enable .Net 3.5 because of "CBS Watchlist Package Missing" problems

I desperately need to enable .Net 3.5 on my 64 Bit Windows 7 Pro SP1 machine. The enable features wizard returns a bland error so I have tried to enable with DSIM enable features and I am getting the following errors:

DISM Package Manager: PID=5764 Error in operation: (null) (CBS HRESULT=0x80070643) - CCbsConUIHandler::Error
DISM Package Manager: PID=5764 Failed finalizing changes. - CDISMPackageManager::Internal_Finalize(hr:0x80070643)
DISM Package Manager: PID=5764 Failed processing package changes - CDISMPackageManager:rocessChanges(hr:0x80070643)
DISM Package Manager: PID=5764 Failed ProcessChanges. - CPackageManagerCLIHandler:rivate_ProcessFeatureChange(hr:0x80070643)
DISM Package Manager: PID=5764 Failed while processing command enable-feature. - CPackageManagerCLIHandler::ExecuteCmdLine(hr:0x80070643)
DISM Package Manager: PID=5764 Further logs for online package and feature related operations can be found at %WINDIR%\logs\CBS\cbs.log - CPackageManagerCLIHandler::ExecuteCmdLine
DISM.EXE: DISM Package Manager processed the command line but failed. HRESULT=80070643

I have therefore run SURT on the machine and I am getting 4 errors with the following summary

Summary:
Seconds executed: 1180
Found 4 errors
CBS Watchlist Package Missing Total count: 1
CBS Watchlist Component Missing Total count: 3

I also ran sfc /scannow and I have uploaded the link to Dropbox below.
Dropbox - CBS.zip

I tried fixing the errors with SFCFIX and it recommended I ask for help because the errors cannot be fixed by SFCFIX.

Please help me.
