I have run as admin, but i keep getting "This Application has encoutnered an unspecified error, please try this patch again." Not sure what is going on.

Make sure all your drivers are up to date.

I just started getting this error today as well. Played for about 4 hours yesterday and then started getting this error when opening the launcher today.

The only time I get this message is when I'm having connection issues. While that may not be the only cause of this error it is the cause when I encounter it. Generally I'll need to restart my computer once I get the error. Often it's after my computer has been on for an extended period of time without a full restart (just putting it to sleep at the end of the day). Even if that's not the reason, for some reason once I get the error the often launcher won't connect until a restart. Often I'll have to restart my router, too, and while that often clears up the issue it doesn't always. I'll also sometimes get that error if I'm tethered to my phone, which will require me moving my phone around and trying again. Once I'm in game my connection is fine, although my ping is about 20~30 ms longer, so it seems that the login server is a little more finicky when it comes to a connection than the game itself.

I am getting this issue today....
