This means the EA AntiCheat installer cannot write its files because the Windows file system transaction log is in a bad state. Resetting that log fixes it. Jump to your situation below or work through the methods in order.
EA AntiCheat Error 701, often shown as Install failed Error 5:701 when you run the installer, is a Windows file system problem rather than an EA AntiCheat fault: the file system's transaction log is in a state that stops the installer writing its files, so Repair, Install and Uninstall all fail the same way. The official fix is to reset the file system transaction log from an elevated Command Prompt with fsutil resource setautoreset true C:\ (using the drive Windows is installed on), then restart and run the EA AntiCheat installer again. If it still fails, run the Windows system repairs sfc /scannow and DISM to fix underlying file system corruption, make sure the installer has write permissions (not set to read-only, run as administrator), and temporarily disable antivirus in case it is blocking the write. Because 701 is a Windows-side block, clearing the transaction log lets the install complete and the game launch.
The Windows file system keeps a transaction log to track changes. When that log is in a bad state, installers cannot commit their files. EA AntiCheat Error 701 is the installer hitting exactly this, so it cannot write its files regardless of whether you choose Install, Repair or Uninstall.
Resetting the transaction log with fsutil clears the block, and a restart lets the installer run cleanly. Windows system repairs fix deeper corruption, and making sure the installer has write permissions and antivirus is not blocking it covers the rest.
“Error 701 fools people into blaming EA AntiCheat, but it is Windows. The file system transaction log has got into a state where nothing can install, which is why Repair, Install and Uninstall all die with the same 701. The fix is one command: fsutil resource setautoreset true C:\ in an admin prompt, then restart and run the installer again. If it still sticks, sfc and DISM clean up the file system, and make sure the installer is not read-only and antivirus is not sitting on it.”

EAAntiCheat.Installer.exe, Properties, and make sure it is not Read-only; run it as administrator.EA AntiCheat Error 701 (Install failed 5:701) is a Windows file system transaction log problem. Reset it with fsutil resource setautoreset true C:\ in an elevated Command Prompt, restart, and re-run EAAntiCheat.Installer.exe. If it persists, run sfc /scannow and DISM, make sure the installer is not read-only and runs as administrator, and disable antivirus while it installs.
If 701 survives the fsutil reset and system repairs, a corrupted user profile or disk error can be the cause; run chkdsk on the Windows drive and try the installer from a clean administrator account. You can also submit your error to us for a tailored fix.
