error code :30005 (StartService failed with 127.)

This issue can be caused by a conflict with your anti-virus @TylerAlison.

What you can try doing is disabling your anti-virus and firewall and then launching the game again.

If it works great, you can add an exception for the game to both. If it does not work then please let me know and we will take it from there.

"launch error failed to start the game" this message pops in when ever i try to launch the game (APEX LEGENDS)

When I saw this error in the past @atomiczxr it was related to an issue with Easy Anti-Cheat. I solved it on my system by adding EAC to my anti-virus white list.

Best thing I can recommend @atomiczxr is taking a couple of minutes to go through the steps here: https://answers.ea.com/t5/Technical-Issues/Easy-Anti-Cheat-troubleshooting-steps/td-p/7437695

I tried every thing,anti virus is already disabled,even origin clean up won't run.

Do you think reinstalling the game or updating my win 8.1 to 10 will solve this problem ?

And one more thing apex would't launch even if i try to run the game manually through the desktop icon.

Those on Windows 8.1 were able to play after a couple quick Microsoft downloads. Check out the solution here: https://answers.ea.com/t5/Technical-Issues/fix-r5apex-exe-win-8-1/m-p/7435727/highlight/true#M4449

Have you tried disabling Windows Defender to see if you can launch it? That way you can see if it's related to that.
