This problem looks exacly the same as an earlier thread I had before:
(
[SOLVED] - Error 80073712 when trying to install updates Server 2012 R2)
I was able to run through some windows updates and am getting an error 80073712 when trying to install the 3 remaining .net updates which are available. I ran through the following steps:
1) sfc /scannow which reported no component corruption
2) dism /online /cleanup-image /restorehealth - completed successfully and reported that the component store corruption was repaired
3) ran SFCFix.exe which reported no issues. Here is the output from the log file:
