Why am I getting forced to install EA App?

On this Thread there is a solution:

To summarise, you firstly need to go to File Manager, and under the View option, tick the box that allows you to see Hidden Files.

Then go to your C:\ Drive, and then you will see the following Folder:

C:\ProgramData\

In that you'll see an Origin Folder, open that.

C:\ProgramData\Origin\

In there you will see this File:

local.xml

C:\ProgramData\Origin\local.xml

Save a copy of that, just in case, so you can put it back if needed.

Now open that File with, say, Notepad, and add the following Key just above the last line:

<Setting key="MigrationDisabled" type="1" value="true" />

Save that.

Go to View and un-tick the option to view Hidden Files.

Then when you launch Origin or a Game, the EA App pop up from the Origin Login, should be gone.

Worked for me.
