Error: 0x80073712 when installing KB 2919355

On the previous page [page 7] you'll find a solution to the KB2919355 problem, allowing you the ability to install 2919355.

Just an FYI... Microsoft can't help you.  

1. they have no clue what's causing the issues thousands of users are having, nor do they understand why it's only affecting some users and not others.
2. There's been a Microsoft employee posting in every single forum thread (including this one) dedicated to this problem and not once have any of them stated anything remotely helpful, giving information that will not only not solve the problem, but will in fact compound the problem and make it worse.

You're not the first person trying to talk to Microsoft Tech Support, and seeming as they [Microsoft] haven't yet figured out what causes this issue, let alone how to fix it, it should tell all tech support can be of no assistance.

EDIT:  The day a press release is issued by Microsoft saying they know what's causing the problems and corruptions and/or they've fixed the problem will be the day users can contact tech support for actual assistance... until then, they're going to tell you worthless, time wasting steps that do not help and cause more harm than good.  The reasoning... they're going to troubleshoot this from a list of instructions as if it's a normal file corruption issued, or a normal problem with Windows Update, of which neither are not.

***KB2919355 Fix that WILL allow the install of KB2919355***

As many discoveries have been made, I discovered this accidentally. and quite by coincidence... 

In order for users, who've been plagued by errors and file corruption, to get a successful completion of KB2919355, all that's needed is to run the 8.1 upgrade installer, and when the 8.1 installer goes to the wait screen after entering the generic product key, start Windows Update for the install of KB2919355

EDIT: It appears, from the input of other users, one must FIRST install the 5 standalone updates included within the Windows Update KB2919355 package, you will then need to restart after the fifth and final standalone, then use Windows Update to install KB2919355 (do not use the standalone installer for KB2919355... use Windows Update).

Steps

1. Run the Windows 8.1 installer from within Windows, as if you're going to do an install repair "upgrade".
2. Enter the generic product key, and upon clicking next, the installer will say wait...
3. Give the installer about 5 minutes, then start Windows Update (it should show the KB2919355 update), and click install.
4. Windows Update will begin downloading the update... if you have a Windows Update cache problem that causes the speed and percentage to remain at zero, don't worry about it and get the update installed first, then you can clear the cache and remove the directories afterwards.
5. The install may fail, don't worry... simply hit install again, making sure the 8.1 installer screen is still on the "wait" screen, as whatever the installer is doing during the "wait" screen is what makes the KB2919355 install possible.
6. KB2919355 should install and Windows Update should request you to restart... simply do so without cancelling the 8.1 installer.  Windows will finalize the update during the shutdown and restart processes.
7. Upon rebooting into Windows, you will have a multitude of additional updates that will need to be installed (around 10, give or take a few), and you can verify the install of KB2919355 by going to "view installed updates"

A few users will need to comment back once they'e performed this in order to see if this automatically fixes the multitude of issues users are facing, and if it doesn't complete successfully, then I can back track what step I took over the past several days in order to figure out what caused this to work for me, but not others if problems occur.

Please help,

I have installed KB2919355 package via windows update,and searchbutton changed it`s place as it should.KB2919355 IS LISTED in the installed updates.

However,windows update continued to offer me KB2919355 again but with a different size-71.8MB.

I downloaded full stand-alone packageKB2919355(including cleancompressionflag.exe) and after I tried to install  it`s components I received messages that they have been already installed EXCEPT one-KB2934018 component(which size is 71.8MB).

I tried to install KB2934018 again(both over windows update and with KB2934018 stand-alone installer)but it failed(ERROR 80073712 EVERY TIME).Cleancompressionflag.exe also failed to fix problem.

I also noticed that Windows Disc Clean-Up maintenance tool IS UNABLE to clean windows update clean-upsection,despite the fact I checked it.

I don`t know what other option I should try.

Thank you.
