How to fix “unarc.dll returned an error code: -6” — FIFA 13 (Exclusive release)

The “unarc.dll returned an error code: -6” occurs during installation when the Unarc library (used to extract compressed installer archives) fails. For FIFA 13 Exclusive or similarly packaged PC installers, that failure typically means one or more of the following: corrupted archive files, insufficient disk space or permissions, problematic RAM or storage errors, conflicting antivirus, or an incompatible installer environment. Below is a concise, practical troubleshooting guide with examples and ordered steps to resolve it.

Fix 4: Check for Corrupt Archives (CRC Error)

If the above methods fail, the issue might be the downloaded file itself. This happens if the download was interrupted or the file was corrupted during the transfer.

How to verify: Most uploaders provide an MD5 or SHA checksum. However, a simpler way to test is to try extracting the setup files manually using a tool like WinRAR or 7-Zip.

  1. Right-click the downloaded ISO or archive.
  2. Select "Extract files..."
  3. If WinRAR gives you a "CRC Error" or "File is corrupt," the download is broken. You will need to re-download the game files or use the torrent "Force Re-check" feature if you used a torrent client.

Quick Fixes (Try in Order)

Solution 3: Run the Setup in Windows 7 Compatibility Mode

FIFA 13 was released in 2012 for Windows 7. The Exclusive Edition repack may not be fully compatible with Windows 10 or 11, leading to unarc.dll errors.

To force compatibility:

  1. Right-click setup.exe (or Unarc.dll) if you can find it.
  2. Select Properties → Compatibility tab.
  3. Check Run this program in compatibility mode for: → Windows 7.
  4. Check Run as administrator.
  5. Click OK.

Then re-run the installer.

Final note

If none of the above works, capture the exact installer log (some setups write an install.log or unarc.log) and search the log for “ERROR” and filenames failing; that often points to the specific damaged file or operation. Use that detail to re-acquire only the broken part or to guide hardware checks.

If you want, provide the exact install log lines or describe where during installation the error appears (percent or filename) and I’ll propose the most targeted next step.

Fixing the Unarc.dll Error Code 6 in usually boils down to a failure in the decompression process during installation. This specific code often indicates that the archive is either corrupted or the system lacks the resources/permissions to unpack it correctly . The "Direct Fix" Checklist Try these common solutions first to get your game running:

Increase Virtual Memory (Page File): If your RAM is overloaded, the decompression will crash. Manually set your page file size to at least 8000 MB (for 8GB RAM) or higher in System Properties > Advanced > Performance Settings > Virtual Memory .

Install "Visual C++ Redistributable" Packages: Missing or outdated runtimes are a frequent culprit. Download the complete MultiPack Visual-C++ to ensure all versions (2005–2022) are installed .

Run as Administrator: Right-click the installer and select "Run as administrator". This grants the program full permission to write files to your drive .

Disable Antivirus & UAC: Security software often flags decompression as suspicious activity. Temporarily disable your Antivirus and User Account Control (UAC) before starting the installation . Exclusive Troubleshooting for FIFA 13

If the basic steps don't work, these more targeted tactics have proven successful for older game repacks:

Limit RAM Usage: Many installers for games like FIFA 13 have a checkbox to "Limit installer to 2GB RAM usage." Checking this prevents the installer from hitting memory limits that trigger the Error 6 .

Short Pathing: Rename your installation folder to something short and simple (e.g., C:\Games\FIFA13). Avoid using spaces or special characters in the folder name, as old decompressors can struggle with complex file paths .

Throttling Your CPU: Modern multi-core processors can sometimes "outrun" older decompression algorithms. You can try setting your Processor Power Management to 99% in Windows Power Options or use Task Manager to set the installer's affinity to fewer cores .

Safe Mode Install: If a background process is interfering, restart Windows in Safe Mode and run the installer from there . Hardware Check

If the error persists across multiple games, it may be a hardware issue:

Disable RAM Overclocking: If you have XMP or custom overclocks enabled in your BIOS, disable them. Unstable RAM timings are a leading cause of checksum and decompression errors .

Check for Disk Errors: Run sfc /scannow in an elevated Command Prompt to repair system files, or use Disk Cleanup to remove temporary junk that might be clogging the process .

The Unarc.dll error code -6 is a common decompression failure typically encountered when installing highly compressed game files, such as

repacks. The specific "exclusive" feature or root cause of error code 6 often points to archive data corruption or a mismatch during the extraction process. Direct Solutions for FIFA 13

Disable Antivirus & Firewall: Antivirus programs frequently flag decompression processes as suspicious and block or "eat" essential files. Disable them temporarily during installation.

Increase Virtual Memory (Pagefile): Repacks require significant temporary memory to unpack.

Go to System Properties > Advanced > Performance Settings > Advanced > Virtual Memory.

Set a custom size (e.g., 4096 MB initial and 8192 MB maximum) for your primary drive.

Clean Installation Path: Ensure the installation folder does not contain special characters or non-English symbols (e.g., #, @, !), as these can cause the installer to misread the directory.

Limit CPU Cores: Some older installers struggle with modern high-core CPUs. You can limit the installer to 2–4 cores via Task Manager by right-clicking the setup process and selecting Set Affinity.

Verify Source Files: Use any built-in file verification tools (like a "Verify BIN files" .exe included with many repacks) to check if your download is corrupted before attempting another installation. System File Repairs

If the issue persists, your system's core decompression files might be missing or corrupted:

Run System File Checker: Open Command Prompt as administrator and type sfc /scannow to repair system-level DLL issues.

Re-register DLLs: Use the command regsvr32 isdone.dll and regsvr32 unarc.dll in an administrator Command Prompt to manually re-register the libraries.

Manual Replacement: Download clean versions of unarc.dll and isdone.dll and place them in C:\Windows\System32 (for 32-bit) or C:\Windows\SysWOW64 (for 64-bit). unarc.dll Error Windows 11 | 2 Ways To FIX | 2021
