Game Won't Launch/Error message that game is running

@yumekumo  The usual cause of this error is a permissions issue.  Try disabling your antivirus/firewall, and if it works, you can set exceptions for Origin.exe, TS4_x64.exe, and TS4.exe.  The same applies to Windows Defender's Controlled Folder Access: disable it to test, then set exceptions as necessary.

If that doesn't help, you can try the other steps listed here:

By the way, your Alienware Command Center software is crashing a lot.  You already have the latest version, so if you're noticing errors, it's a good idea to uninstall it, and I guess reinstall if you want to keep using it.

The Realtek driver also crashed, and Dell offers a newer version, so that should probably be updated too.
