To fix a compare.dll error without downloading anything from third-party websites, you need to repair or restore the file using built-in Windows tools or the official software that uses it. Third-party DLL download sites are often unsafe and contain malware.

Here are the safest, most effective ways to fix the issue:

Run SFC and DISM Scans

Windows has built-in tools to find and replace missing or corrupted system files automatically.

Open the Start Menu.
Type cmd, right-click Command Prompt, and select Run as administrator.
Type sfc /scannow and press Enter.
Wait for the scan to finish and restart your computer.
If the error persists, open the administrator Command Prompt again.
Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.

Check the Recycle Bin

Sometimes files are deleted by accident.

Open the Recycle Bin on your desktop.
Search for compare.dll in the top-right search bar.
If you find it, right-click the file and choose Restore.

Reinstall the Problematic Program

If the error happens when you open a specific application, that program's installation is likely corrupted.

Open Settings (Windows Key + I).
Go to Apps > Installed apps.
Find the program causing the error.
Click the three dots next to it and select Uninstall.
Restart your computer.
Install the program again using its original official installer.

Restore Your System

If the error started happening recently, you can roll Windows back to a time when everything worked.

Type Control Panel in the Windows search bar and open it.
Search for Recovery in the Control Panel search bar.
Select Recovery > Open System Restore.
Click Next, choose a date before the error started, and follow the prompts.

Run a Malware Scan

Sometimes malware deletes, locks, or mimics DLL files.

Open Windows Security from your taskbar or settings.
Go to Virus & threat protection.
Click Scan options, select Full scan, and click Scan now.
