Re: DAI won’t launch

First thing...what anti-virus do you use??  Try disabling, removing or at minimum whitelisting DAI, DAI saves folder(if exists) and Origin app program. 

Next, we need a DxDiag file to start with, so we can get an idea of what's going on in the system.

Last, things like Razor products program, TeamViewer 13, along with Anti-viurs, and a whole host of other programs can interfere with DAI.  One method to find out if this is an issue is a clean boot of your system, which boots up the system with limited programs and most times it eliminates cross program interference.  I say sometimes because some clean boots still have issues with Anti-virus even on a clean boot that isn't supposed to have them active....so I have to assume that other programs can do the same.
