Fix “DLL File Missing” Error in Windows 7 Easily

DLL (Dynamic Link Library) files are essential components in Windows that store reusable code and procedures used by multiple programs simultaneously.

For example, when an app needs to perform a function (like saving a file or connecting to the internet), it can use the instructions stored in a DLL file instead of writing the code itself. This makes Windows faster and more efficient.

However, when a DLL becomes corrupt, missing, or outdated, you may encounter frustrating errors such as:

• msvcp140.dll missing
• DLL File Missing

These errors can prevent certain applications from starting or running correctly.

How to Fix “DLL File Missing” Errors in Windows 7​

Here are some proven troubleshooting methods to restore missing or corrupt DLL files and get your PC running smoothly again.

1. Reboot Your System​

It may sound too simple - but it works! Restarting your computer often reloads essential system files that might have failed to initialize properly.

If your system becomes unresponsive, hold down the power button to force a manual reboot.

2. Update Windows and Drivers​

Outdated system files are a common cause of DLL issues.

To check for updates:

1. Open Control Panel → System and Security → Windows Update
2. Click Check for updates and install any available patches.

Don’t forget to update your device drivers as well! Old or incompatible drivers can also cause DLL errors.

3. Recover Deleted DLL Files​

Sometimes, DLLs are deleted by mistake. Here’s what to do:

• Check your Recycle Bin for the deleted file.
• If permanently deleted, try using a file recovery tool (like Recuva).

Note: This method won’t help if the DLL file was already corrupted before deletion.

4. Reinstall the Problematic Application​

If the DLL error only appears when launching a specific app, reinstall it:

1. Go to Control Panel → Programs and Features
2. Uninstall the affected program
3. Restart your computer
4. Download and reinstall the latest version of the software

This refreshes all dependencies and can often fix the issue instantly.

5. Run a System File Check (SFC Scan)​

Windows has a built-in tool to detect and repair missing or corrupt files.

To use it:

1. Open Command Prompt as Administrator
2. Type the following command and hit Enter: sfc /scannow

1. Wait for the scan to finish - it may take several minutes.
2. Restart your PC once the process completes.

This will automatically replace any damaged system DLLs with fresh copies from Windows.

Final Tip: Scan for Malware​

Malware and viruses can delete or modify DLL files. Use Windows Defender or a trusted antivirus program to perform a full system scan regularly.

If none of these methods work, your last resort is to reinstall Windows 7 to completely refresh your system.

Pro Tip: Always back up your important files before making system changes. Prevention is better than cure!
