I don't know that program so can't advise on it but prior to trying the unknown, I would always create a system image first, but first let's try some of Windows own repair tools.
Windows has its own update troubleshooter which you can find by clicking on the Start button - Settings cog - Update & Security - Troubleshoot then click on the one for Windows Update.
Others are as follows -
Right click on the Start button and select Command Prompt (Admin) or Powershell (Admin) and enter these cmds and then see if the update will install.
dism /online /cleanup-image /startcomponentcleanup
That one can take a while to run.
dism /online /cleanup-image /restorehealth
sfc /scannow
The last one will tell you if there is any remaining corruption or not.
If the sfc comes back clean and the update still gives you an error message then copy & paste these cmds to the cmd prompt where they will auto run except perhaps for the last one where you will need to press enter.
These cmds reset the update components and while they will remove the update history, they will not effect already installed updates.
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
Close off the cmd prompt or Powershell window by entering exit, reboot and try the update again.
Another cause of this WD update error code is because of what you could have installed, so if you still have problems then see if a clean boot will resolve.
Right click in the task bar and select Task Manager.
If this is the first time you've accessed Task Manager in Win 10 then you will be presented with a blank window - click on More details bottom left where the pane will then populate.
Under the Start-up tab disable all items, click on File/Exit then on the desktop in the search box type msconfig and press enter when System Configuration comes up.
Under the Services tab check the box to Hide all Microsoft services then click on Apply - OK - Restart and then see if it has resolved.
To restore the non-MS sevices, go back into msconfig and check the button for normal startup which will require a reboot to effect, but if you get the error code again with subsequent updates and disabling all non-MS services resolves, you will need to go back into msconfig, disable them again and after the reboot enable just one of those at a time to see which one is causing the problem and leave that one unchecked.
Generally you don't need any items enabled under Start-up in Task Manager.
Microsoft haven't come up with a solution yet as to why this occurs so I would be distrustful of any 3rd party program which in all likelihood will be a paid for program which could do more harm than good.
