How to Fix msvcp80.dll Errors Without Downloading the File

You do not need to download standalone DLL files from untrusted internet websites, as they often contain malware or are outdated. Instead, use these native built-in Windows repair tools.

1. Run the Deployment Image Servicing and Management (DISM) Tool

This tool repairs the underlying Windows image and fixes corrupt system files.

Press the Windows Key.
Type cmd.
Right-click Command Prompt and select Run as administrator.

Type this command and press Enter:

DISM.exe /Online /Cleanup-image /Restorehealth

Wait for the process to complete 100%.

2. Run the System File Checker (SFC) Scan

The SFC tool scans all protected system files and replaces corrupted ones with a cached copy.

Keep the Command Prompt (Admin) window open from the previous step.
Type this command and press Enter:
```
sfc /scannow
```
Do not close the window until the verification is complete.
Restart your computer.

3. Restore the File from the Recycle Bin

If you accidentally deleted the file yourself, check your trash.

Open the Recycle Bin on your desktop.
Search for msvcp80.dll.
Right-click the file and click Restore.

4. Reinstall the Program Causing the Error

If the error only happens when opening one specific app, that app's copy of the file is broken.

Open Settings (Windows Key + I).
Go to Apps > Installed apps.
Find the problematic application.
Click Uninstall.
Reinstall the app using its original installer file.
