Starting DA:I after long time
It is saying that the game needs origin yet you say you have the latest version installed. Which usually means something got out of sync between the programs. If it works the way it should in the repair, you shoudln't have to redownload or reinstall your DAI program, but you will probably have to reinstall Origin.
I would start by totally closing origin, making sure all processes and such linked to it are closed, then restart Origin and see if you can launch the game from Origin. If this doesn't work, then close origin, and make sure all processes are closed and then reinstall Origin from the EA website. You can make up your mind if you want to do Origin reinstall two different ways, but if a simple full restart didn't fix it, you will probably need to go the full process of clearing the Origin Cache and then doing the reinstall. Once you have Origin reinstalled, AND set the install location for games to the proper location where your games are, it SHOULD be ready then maybe run a repair on the DAI install and verify all files. This SHOULD allow everything to work as it is designed to work...
