How to get 1903 or do I fix 0x800703f1 first?

[Gary742]

When I tried to do a windows update, I got the error between the dashed lines

-----------------------------------

Your device is missing important security and quality fixes

There were problems installing some updates, but we'll try again later.

2019-10 Cumulative Update for .NET Framework 3.5, 4.7.2 and 4.8 for Windows 10 Version 1809 for x64 (KB4524099) - Error 0x800703f1

2019-12 Cumulative Update for Windows 10 Version 1809 for x64-based Systems (KB4530715) - Error 0x800703f1

-------------------------------------

When I ran winver, I learned that I am, in fact, on 1809, not 1903



So, do I
- try to update to 1903 - HOW?

or

-try to fix this 1809 error 1st??

I'd try and correct the errors first. normally errors will kill the process. I use a healthfix.bat as admin for my clients and this has been average 99% a total fix. copy the below to notepad, save as Healthfix.bat then run as admin.... or you can do 1 @ a time. if you havd ADK installed uninstall first then run bat
