Win 10 1703; How to fix broken DISM and hence Windows Update?

error 193 cannot be cleared via DISM or SFC,
Its either the install/repair of the API or a clean install
The only folder that can establish the missing or corrupt entries causing it, is - System32/downlevel...API folder..
(This problem has no specific MS related fix documentation, and causes an internal corruption within DISM.)

Although the OP referenced a specific file as being missing, it may not be the relevant file.

api-ms-win-core-file-l1-2-0.dll;11;30.10.2015 07:28;30.10.2015 07:28
api-ms-win-core-file-l1-2-1.dll;0;30.10.2015 07:28;30.10.2015 07:28

in the above, although 2 different files, the error is identified by the 0 it should be greater than 10

[SOLVED] [10ProV1511b10586 x64] Can't upgrade, DISM Error 193, sfc finds nothing
in the thread a number of files needed to be corrected

If the API is missing them it will have to be imported- note the dates MUST be the same

I'm the OP. Thank you! After a week of searching, that's the most definitive statement I've seen on this error! Sounds like you are familiar with it.

Yes, in desperation I put a copy of the "missing file" that I got from a healthy 1709 laptop into the downlevel directory on this 1703 desktop. Made no difference. (I have removed it.)

I had seen ref to the downlevel directory in other threads dealing with the same problem, but didn't (and still don't) know how to proceed. I did try a 1703 repair in place with no success. (IIRC, the installer errored out after about 85% completion of the file installation phase.)

api-ms-win-core-file-l1-2-0.dll;11;30.10.2015 07:28;30.10.2015 07:28
api-ms-win-core-file-l1-2-1.dll;0;30.10.2015 07:28;30.10.2015 07:28

Don't understand. Are you saying the files are misnamed? You mean the "0" in the file name? The "0" vs. the "11" between the two semicolons? They are not part of the file name - what are they? My downlevel directory does contain those two files, but with dates corresponding to Win 10, 1703, 15063.850.

As I say I'm not missing two files with those precise names.

I have a fresh, mounted 1703 iso, but I don't see a downlevel directory in it. (There are directories with many manifest folders, but I don't know how to extract and install files from them.) I will study that thread more carefully, but it looks like the solution - the SFCFix script - was prepared specifically for that user. If someone could instruct me on how to do that, I'd most appreciate it (as will future searchers LOL).

Many thanks, -Ron

EDIT - Looks like the program SFCFix.exe can be used without a script, and is purported to fix errors that sfc /scannow cannot. https://www.ghacks.net/2015/11/06/sfcfix-comes-to-the-rescue-when-sfc-scannow-cannot-repair-windows-file-corruption/ But it's no longer supported. Anyone been successful with it in Win10?

Hi Ron,

That downlevel folder is a bit of a mystery, there is a basic set of API's but its added too depending upon what you have installed, my W10IP is much larger than yours even tho i've only got 4 programs on it!!!

Must admit been looking at that error code for a while, and quite a lot over the last few days.

Did you actually view the ouput post#18, you will need to register.
I tried to recreate the output in the same format, with the extra detail, but couldn't can you??
If you can then we can replace the corrupt entry
As for "0" id have to guess its some kind of version number

One more thing
Those entries should be about 7kb got any with 0

Im still hunting

Roy

Hi Ron,

see its sorted,

Suspect it waited for your active times to pass before it downloaded and installed the upgrade, after those downlevel fixes.

Roy

@topgundcp Thanks, I'll look into that. EDIT - those updates are for 16299. I'm still on 15063 trying to get to 16299. Tx anyway.

I don't understand what you are saying here. The program will allow you to download all available updates for MS Office, Windows 7/8/10. So it depends on what you need to download.

If you want the update for 10563 then put a check mark on those. You can also download all 16299 to update from 10563, skipping all the updates in between.
