Common Causes of Windows Error 87
Common Causes of Windows Error 87 and How to Fix Them
Windows Error 87 is a common issue that usually indicates invalid parameters or misconfigurations during system operations. Understanding the root causes can help you troubleshoot and resolve this error quickly.
1. File Size Limitations on FAT32 Drives
If you try copying files larger than 4 GB to a FAT32-formatted drive, Windows Error 87 will occur due to the file system’s size restrictions. To fix this, consider converting the drive to NTFS or splitting large files.
2. Incorrect Command Syntax or Outdated Tools
Running commands with wrong syntax, using outdated or incompatible versions of system tools, or missing essential drivers like Wofadk.sys (required for DISM) can trigger Error 87. Always verify command parameters and update your tools.
3. Complex or Corrupted Access Control Lists (ACLs)
Corrupted or overly complex ACLs, excessive ACL entries, or using legacy permission tools on modern Windows versions often lead to parameter errors. Error 87 indicates a failure due to an incorrect parameter in a requested path, so using built-in utilities like ICACLS to manage permissions properly can help prevent this issue.
4. Software Conflicts and System File Corruption
Conflicts between software, damaged Windows system files, incomplete updates, or registry errors can cause Windows Error 87. Running System File Checker (SFC) and DISM repair commands can help restore system integrity.
5. Malware and Unauthorized System Changes
Malware infections or unauthorized modifications may corrupt critical system components, resulting in Error 87. Perform a thorough antivirus scan and system restore when necessary.
6. Lack of Administrative Privileges and Incompatible Environments
Executing commands without administrator rights, running them in unsupported environments, or referencing inaccessible resources such as malformed UNC paths or unavailable network shares often causes this error. Ensure you have proper permissions and resource availability before running commands.
By understanding these common causes and applying the recommended fixes, you can effectively troubleshoot and resolve Windows Error 87 to maintain smooth system performance.

Typical Scenarios Where Error 87 Appears
Common Causes and Scenarios for Windows Error 87
Windows Error 87 is a frequent issue that occurs during various system operations, especially when using Deployment Image Servicing and Management (DISM) commands. One of the most common reasons for encountering Error 87 is incorrect command syntax—such as typing “DISM/online/cleanup-image/checkhealth” without proper spaces—leading to the system not recognizing the command properly.
To avoid this, always ensure correct spacing and syntax when running DISM commands.
Another typical scenario for Windows Error 87 is running DISM without administrative privileges. On systems with User Account Control (UAC) enabled, failing to launch the Command Prompt or PowerShell as an administrator will often result in this error.
Always use elevated permissions to execute system-level commands. Lack of elevated privileges can trigger Error 87 during execution, so it is important to run these commands as an administrator.
Windows Update processes can also trigger Error 87. If your updates are pending, corrupted, or partially installed, trying to repair system images with DISM might cause this error. This often happens after failed or incomplete Windows updates.
Additionally, running activation or licensing commands with invalid parameters or mismatched tool and image versions can cause Error 87.
Lastly, corrupted system files or component store corruption can prevent DISM from functioning correctly, leading to Error 87 during system health checks or repairs.
Resolving these underlying file integrity issues is crucial to prevent recurring errors.
Diagnostic Steps to Identify the Source
How to Fix Windows Error 87: Step-by-Step Diagnostic Guide
Encountering Windows Error 87 can be frustrating, but with the right troubleshooting steps, you can quickly identify and resolve the issue. This error commonly occurs due to incorrect DISM command syntax, lack of administrative privileges, outdated Windows updates, or system corruption.
Follow this comprehensive guide to fix Windows Error 87 effectively.
1. Verify DISM Command Syntax
Ensure your DISM command uses the correct format and switches. A common and effective command is:
`DISM /Online /Cleanup-Image /RestoreHealth`
Double-check for any misplaced spaces, slashes, or typos, as even a small mistake triggers Error 87.
2. Run Command Prompt as Administrator
Windows Error 87 often appears if you run DISM without administrative rights. Always launch Command Prompt by right-clicking and selecting “Run as Administrator” to avoid permission-related errors.
3. Check Windows Update Status****
An outdated or incompatible Windows version can cause DISM failures. Go to Settings > Update & Security > Windows Update to confirm your system is fully updated.
4. Scan for System Corruption
Use the System File Checker tool by running `sfc /scannow` in the elevated Command Prompt.
Additionally, review DISM logs located at `%windir%LogsDISMdism.log` for detailed error information and signs of system corruption.
By following these diagnostic steps, you can efficiently troubleshoot and fix Windows Error 87, ensuring your DISM commands run smoothly and your system stays healthy.

Solutions and Workarounds for Error 87
How to Fix Windows Error 87: Effective Solutions and Workarounds
Encountering Windows Error 87 can disrupt your workflow, but with the right troubleshooting steps, you can quickly resolve this issue. This comprehensive guide covers proven methods to fix Error 87 by addressing software conflicts, corrupted system files, and problematic DLLs.
1. Perform a Clean Boot to Eliminate Software Conflicts
Start by opening the System Configuration tool (msconfig). Disable all non-Microsoft services under the Services tab and then use the Task Manager’s Startup tab to turn off all startup programs.
Restart your PC to see if Error 87 still occurs. This clean boot process helps isolate third-party software causing the problem.
2. Run the DISM Tool to Repair Windows Image
Open Command Prompt as Administrator and execute the command:
`Dism /Online /Cleanup-Image /ScanHealth`
Ensure your DISM version matches your Windows version to prevent compatibility issues. Avoid interrupting the scan, as DISM will detect and fix issues within the system image that might trigger Error 87.
3. Use System File Checker (SFC) to Repair Corrupted Files
In an elevated Command Prompt, run:
`sfc /scannow`
This command scans for and repairs corrupted or missing system files that can cause Error 87, restoring system stability.
4. Fix Specific DLL Issues (e.g., atig6pxx.dll)
If Error 87 references a specific DLL like `atig6pxx.dll`, rename the file by adding a `.bak` extension (e.g., `atig6pxx.dll.bak`) and then reboot your PC.
This prevents the faulty DLL from loading and may resolve the error.
5. Perform a Clean Windows Reinstall as a Last Resort
If none of the above steps work, back up your important data and perform a clean reinstall of Windows.
This will eliminate any persistent system-level issues causing Error 87.
By following these targeted solutions, you can effectively troubleshoot and fix Windows Error 87 to restore optimal system performance.
