How to Fix the Error Without Downloading

Do not download individual DLL files from third-party websites, as they often contain malware or outdated versions. Use these built-in Windows tools to fix the error safely.

1. Run the System File Checker (SFC)

This tool scans and automatically restores corrupted Windows system files.

Press the Windows Key.
Type cmd.
Right-click Command Prompt.
Select Run as administrator.
Type sfc /scannow and press Enter.
Restart your computer after the scan finishes.

2. Run the DISM Tool

If SFC fails to fix the issue, the Deployment Image Servicing and Management (DISM) tool will repair the Windows system image using official Windows Update servers.

Open Command Prompt as administrator (same steps as above).
Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
Wait for the process to reach 100%.
Run the sfc /scannow command one more time.

3. Install Pending Windows Updates

Missing system updates can cause API set libraries to become desynchronized.

Press Windows Key + I to open Settings.
Click Update & Security (or Windows Update).
Click Check for updates.
Install all available updates and restart your PC.

4. Reinstall Visual C++ Redistributables

This specific DLL error often triggers when an application cannot bridge to the universal C runtime. Reinstalling the official packages restores these connections.

Open the Control Panel.
Go to Programs and Features.
Look for Microsoft Visual C++ Redistributable (specifically 2015-2022 versions).
Right-click the package and select Change, then click Repair.
Alternatively, download the official unified installer directly from the official Microsoft support website if the repair option is missing.
