Re: Mouse Stops Working As I Enter The Sims 4 Game

@Carlieseuss  Try unplugging the mouse and restarting your computer with it unplugged, then reconnecting it afterwards.

If that doesn't help, manually uninstall the driver.  Hit Windows key-X, select the Device Manager, expand the Mice and pointing devices section, select your mouse, and uninstall.  Unplug it, restart your computer again, and when you plug the mouse back in, Windows should download a fresh copy of the appropriate driver.

I’m using a laptop, so the mouse is part of the keyboard, and is working fine for anything other than the sims. 

I believe I did try deleting the driver, but will try that again. 

@Carlieseuss  I thought you meant a standalone mouse, not the built-in touchpad.  (The touchpad is called a touchpad or sometimes a trackpad, not a mouse.)  The fact that you're having trouble with the touchpad might make things more complicated.  It's worth reinstalling the driver package for your Surface, which Microsoft provides.  Find your model on this page:

https://learn.microsoft.com/en-us/surface/manage-surface-driver-and-firmware-updates

Then click the link and you'll be able to download the appropriate driver package.  It's fine to run the package over the top of the existing install rather than uninstalling everything beforehand.

It's also worth testing the game in windowed mode.  Go into Documents > Electronic Arts > The Sims 4, open options.ini, search for fullscreen , and set it to 0 (zero).
