Attention Windows 8.1 x64 Users:
During development and testing, it’s come to our attention that there are some very important Windows KB updates for this version of the Operating System. Instead of including the 800MB for all users, we instead wrote this supplemental information Article.
How to check if you have the KB installed
If you keep up-to-date with your Windows Updates you should be all set! But, in case you haven’t, you can check if this is installed when you go into "Add Remove Programs" in Windows 8.1. Along the left side, there’s a feature to view your "Installed Windows Updates." This list is pretty long, but if you are able to see KB2919355 (800 megs) and KB2919442 (about 10 megs), then you’re good to go!
Where do I download these?
If you don't have these, here are the Microsoft links for the two System Updates we are referring to.
https://www.microsoft.com/download/details.aspx?id=42162
- NOTE: Even though the KB number is newer, this one should be installed first
https://www.microsoft.com/download/details.aspx?id=42335
- NOTE: This will download about 4 files, and there is a specific order on which these need to be installed.
