I wan't to play post stroke but can't use my mouse right now!

jman81647  If you only have the Steam version of Sims 4 installed, the EA App will automatically install your packs into the Steam version.  If you happened to have two copies of Sims 4 installed, the App could get confused about where to install the packs, as has happened to a lot of players.

jman81647  Steam will install a new game into whatever you've designated as the Steam library.  You can move it after the fact if necessary, or create a new library beforehand.

It sounds like you wouldn't need to change anything, but if you wanted to, it should be simple enough.

jman81647  You don't need to buy the game again on Steam.  You can redeem the base game for free, uninstall the EA App version, install through Steam, and download only your packs (not another copy of the base game) through the EA App.  When done correctly, everything will load as if you owned it in Steam.

Best of luck with your recovery.

Jman, if your left hand is still working properly, you may want to try using your mouse with that hand. I have a long history of hand issues and switching the mouse between hands is I what I did in that situation. Also, as you recover more from your stroke (sorry that happened to you, btw), if you still find using the traditional 3 button mouse an issue, you may want to consider giving a vertical mouse a try; they are very comfortable to use and Logitech's come in two sizes, as well as for right and left hands. There are also joystick style mouses as well. Take a look online for "vertical mouse" and you'll be surprised at what you'll find. Good luck in your search and your recovery!
