***It appears I have stumbled upon a fix for all KB2919355 issues and will be posting this to numerous forum threads***
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 installed goes to the wait screen after entering the generic product
key, start Windows Update for the install of KB2919355
Steps
- Run the Windows 8.1 installer from within Windows, as if you're going to do an install repair "upgrade".
- Enter the generic product key, and upon clicking next, the installer will say wait...
- Give the installer about 5 minutes, then start Windows Update (it should show the KB2919355 update), and click install.
- 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.
- 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.
- 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.
- 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.
