Re: HELP!
@aelisme0 Yes, you can install the game on a flash drive. But it would be best to uninstall the copy on your internal drive first. If you can't do that through the EA App or Steam, you can remove it with Revo Uninstaller (the free version is fine). Here's a guide for doing so in case it helps:
Be sure to rename the Sims 4 folder in Documents > Electronic Arts to something that doesn't include "Sims 4" so that Revo doesn't flag it for deletion. This folder contains your saves and other user data, not the game's program files.
