Another pervasive, yet often overlooked, cause of error code -6 is the overzealous intervention of antivirus software or Windows User Account Control (UAC). Security programs frequently quarantine or block the unarc.dll file or the temporary decompression buffers it creates, misidentifying them as threats due to heuristic analysis of installer behavior. To test this, temporarily disable your real-time antivirus protection and any ransomware protection shields before running the installer. Crucially, also run the setup executable as an administrator: right-click on setup.exe and select “Run as administrator.” This elevates permissions and prevents UAC from restricting the installer’s write access to temporary folders. If the installation succeeds with antivirus disabled, add the entire FIFA 13 installation folder and your system’s temporary files directory (e.g., %temp% ) to your antivirus’s exclusion list, then re-enable protection.
