I am not sure why forum moderator would do that till the thread is dead for a certain amount of time or the OP post saying they got it working.

As for my suggestion about updating and installing things, when I did a fresh install of my windows 10 since windows update was failing to install 1607 completely, I did not install any of my programming applications. When I went to install FF14, it told me I did not have some framework. I took a look and sure enough, I did not have any installed. It looks like only directX (whatever comes through the windows update) was installed.

I went ahead and grabbed the 2 I mentioned and things worked fine for me. This is why I am suggesting to others to try it if they do not have it installed as I believe FF14 is using them.
