Windows 10: Error 0x80073701 trying to run KB4598242

Have a Surface Pro which keeps giving an error at about 36% installation. Have been trying for a few weeks but keep getting this error. Have run Windows Troubleshooter and a sfcscan which did find some errors that it fixed not unusual. Have two other computers which installed this update with no problem. So why this one? They all have the same programs installed as I have to take my work with me on the road.

Hi, there appear to be errors in your log. What was the final statement on the screen?

Looks like the two key things are the error number 0x80073701
and ERROR_SXS_ASSEMBLY_MISSING

Have you also checked absolute basics:
- check your disk (e.g. HDTune v2.55 free Health and Error Scan tabs
- if ok, run
chkdsk c: /scan
from an admin command or Powershell prompt
