Another launcher is already running - EasyAntiCheat

I was able to fix this by using Add/Remove Programs to uninstall Razer Synapse that was sneakily hiding on my computer from way back when.

A workaround that has been working for me is openning the task manager (ctrl + shift + esc) and entering the tab Details before launching. Then, right after the launch, I close the first BF2042 process that appears in the Details tab. A second process is issued a few seconds after the first (it seems like the EA app is really launching the game twice). You must be reasonably fast to close the first process before the second one detects it.

Are you guys using the trail version by any chance? Cause this is the version I'm using right now, and it is doing that launching the game twice thing. It seems it could be trying to launch the paid version and trial verison at the same time. However, in addition to this problem I also receive this error (Untrusted file system C:\Windows\System32\ws2_32.dll). Anyone else getting this error, or something like it that's preventing the game from launching?

Same issue here. I will try the task manager trick ... hope they sort this out, very annoying

Dans mon cas je dois fermer EasyCheat qui demarre aussi 2 fois, je ne vois pas Battlefield dans le task manager, juste Easy Cheat.

Jèespere que ca peut aider qqun

Still having these problems even after release. Tried all the same things as OP plus completely reinstalling GPU drivers using DDU. Also tried the 2 suggested solutions that worked for others and those also did not work.

I've been speaking to EA Technicians the past couple of days. I was informed that they are working on a patch for it. I'm not sure when this will happen though.
