Error: 0x80073712 when installing KB 2919355

Also since you technically still don't have "2919355" installed, you will still be affected by the "no updates if 2919355 not installed by XXX" right?

Justin, I believe I can answer this part from personal experience. If you have not installed all of the subfiles, MU will continue to tell you that KB2919355 still needs to be installed, although the size of the file will be smaller depending on how many are left to install. It appears that all future security patches depend on whether or not just the subfile KB2919355 is installed. I have not yet got subfile KB2932046 installed yet this past Patch Tuesday I received all patches based on my having the Package KB2919355 installed. For Now, I just don't/can't install the remaining part until a solution is found.

I appreciate all the time and research you've put into this. I received what seems to be standard 8.1 media; during install it asked if I wanted to let it use Windows Update during the install (or something similar). However as I metioned right after it finally started up I turned off auto-updates. I did check what updates it wants to install; there are quite a few, and interestingly a number of them say "for systems without 2919355 installed". I didn't install any, sounds like it's ok to let it install everything but 2919355. I might go ahead and do that.

I haven't run any DISM commands either. I'm afraid to screw it up by doing the wrong order now. I probably should, to see if the repair install truly repaired the corruption. Then make a Restore Point and maybe also a full backup.

After that then I could try the 219355 standalone installer (no way will I let Windows Update do it). If it buggers my system I could roll back to the restore point.

At what point did the /scannow start reporting corruption? After attempting the standalone 2919355?

The files should be on the root.  Run the setup from within windows.  Depending on if you have a UEFI setup with a bios locked key will determine if you'll be required to input a product key. If you are required to, the 8.1 Pro generic key is XHQ8NC3MCJRQXB6WCHYGC9WKB.  If you have a different version of windows, google "<windows edition> generic product key".  If you have to use a generic key to install, you'll need to manually activate windows through PC Settings with your activation product key.

Select the option to keep everything the same [paraphrased], which should be the 1st option out of three and should be located at the top of the window.  Let the install do it's thing and be patient as it can take a while.  I've had it take as little as 30 - 60 min, but when I did it yesterday to fix the same problem you're having, it took a few hours.  You're not going to be able to use your pc during this time.

 

I put the files from the 8.1 DVD onto my desktop, ran the setup using the included key and doing the "keep everything the same" option.

After it finally reinstalled, I turned off auto updates. Update history is blank but I'd wager the corruption is still there. MS Tech support is supposed to call on Friday, $20 says he just attempts to install 2919355, has it fail, and then tells me to just reinstall windows 8.1 completely from the media he sent.

I will then say that's no an acceptable solution.

One thing that concerns me, you say your procedure cleans up the corruption, but 2919355 still won't install after that - but does the attempt to install it corrupt the component store again?

I don't know what version of install media you received, but if it doesn't contain update files, then I would go into windows update, change the setting to prevent downloading and installing automatically, run windows update and if updates (besides 2919355) are available, I would recommend installing them.  2919355 won't even show until a specific update is installed, as this update is a prerequisite to installing 2919355.  I did the install repair and installed all updates until 2919355.  I then ran /restorehealth and sfc /scannow to make sure no errors were present, then I downloaded the standalone installers for all updates packaged within the Windows Update version of 2919355.  I installed the updates from smallest size to largest, which would culminate in standalone KB2919355.  Everything installed fine, except the standalone 2919355, which has failed 4 times thus far.  running /startcomponentcleanup still runs fine. as does /restorehealth, but /scannow now reports a corrupted store even though /restorehealth does not.  I've yet to narrow down why and will be investigating.
