Error code -6 with unarc.dll means the installer cannot read the compressed data correctly.
Do not blame FIFA 13 – the game itself is fine. Focus on re-downloading and turning off security software during installation.
Once installed successfully, you can re-enable antivirus and play FIFA 13 normally.
FIFA 13 remains a classic for football gaming fans, but installing it on modern Windows systems often triggers the dreaded "unarc.dll returned an error code -6" message.
This specific error means the installation archive could not be decompressed. This usually points to corrupted setup files, insufficient system memory, or overprotective security software.
Follow this step-by-step guide to bypass error code 6 and get FIFA 13 running smoothly. 🛠️ Quick Fixes to Try First
Before diving into complex system changes, try these quick solutions that resolve the majority of extraction errors. 1. Run Setup as Administrator
Windows often blocks installer actions due to restricted user permissions. Right-click the FIFA 13 setup.exe file. Select Run as administrator. Grant permission and proceed with the installation. 2. Disable Antivirus and Windows Defender
Antivirus programs frequently flag large compressed game files as false positives, blocking the unarc.dll file from extracting them. Open Windows Security > Virus & threat protection. Click on Manage settings. Toggle Real-time protection to Off.
Remember to turn it back on after the installation is complete. 3. Change the Installation Directory
Long file paths or special characters in folder names can cause extraction failures.
Create a new folder directly in your main drive (e.g., C:\Games\FIFA13).
Run the installer again and choose this new folder as your destination path. 💻 Advanced System Troubleshooting
If the quick fixes do not work, the issue likely stems from your system's memory handling or missing system files. 4. Increase Virtual Memory (Paging File)
Error code 6 often occurs when your system runs out of physical RAM during heavy decompression. Increasing your virtual memory gives Windows more breathing room.
Press the Windows Key, type Advanced system settings, and press Enter.
Under the Advanced tab, click Settings in the Performance section.
Go to the Advanced tab and click Change under Virtual Memory.
Uncheck Automatically manage paging file size for all drives.
Select your system drive (usually C:) and click Custom size.
Set the Initial size to 4096 and Maximum size to 8192 (this allocates 4GB to 8GB of virtual RAM). Click Set, then OK, and restart your PC. 5. Re-register the Unarc.dll and ISDone.dll Files
Sometimes the Dynamic Link Library (DLL) files responsible for extraction become unregistered in the Windows registry. Type cmd in the Windows search bar. Right-click Command Prompt and select Run as administrator. Type regsvr32 isdone.dll and press Enter. Type regsvr32 unarc.dll and press Enter. Restart your computer and try installing FIFA 13 again. 6. Check Your RAM for Errors
A faulty stick of RAM is a notorious culprit behind random unarc.dll errors.
Type Windows Memory Diagnostic in the search bar and open it. Select Restart now and check for problems.
Your PC will restart and scan your hardware for memory physical defects. If it finds errors, you may need to replace a RAM stick. 📦 What to Do If the File is Corrupted
If none of the system fixes work, the installation archive itself is likely broken.
Re-download the game: If you downloaded a digital copy, a single lost packet during download can corrupt the compressed archive. Delete your current installer and download it again.
Verify game files: If you are using a launcher like EA App, use the "Repair" or "Verify Integrity" option in your game library to fix broken files automatically. Error code -6 with unarc
