msvcp140.dll is missing

Name: Quickfix AI
Author: Quickfix AI

What this error means

This message appears when a Windows app cannot find msvcp140.dll, a file that is part of the Microsoft Visual C++ runtime. Many programs need it to start, so the app may open and then close, or it may not launch at all.

You may see this after installing a new app, updating Windows, or opening older software that depends on Microsoft components that are not installed correctly.

Common causes

1The Microsoft Visual C++ Redistributable is missing or damaged
2A Windows update, app update, or repair process removed or replaced the file incorrectly
3The app was installed incompletely or the file was quarantined by security software

How to fix it

Restart your computer. A restart can clear a temporary problem if the file was not loaded correctly.
Install or repair the Microsoft Visual C++ Redistributable for your app. Download it from Microsoft, then install the version your program needs. If you already have it, choose the repair option if available. On many systems, both the 64-bit and 32-bit versions are needed.
Update Windows. Open Windows Update and install all available updates, then restart again. Some runtime files are included through normal Windows updates.
Reinstall the program that shows the message. Use the app’s normal uninstaller, then install a fresh copy from the official source. This can restore missing program files and dependencies.
Check your security software. If antivirus or Windows Security recently quarantined the file, restore it only if you trust the app and the source. Then add the program back through a clean reinstall if needed.
Run a Windows repair scan if the problem continues. Use built-in repair tools such as System File Checker and DISM to look for damaged Windows files. These tools are safe and may fix missing system components.
Get help from the app vendor or Quickfix support. If only one program is affected, the app may require a specific runtime version or a known fix from the developer.

Recommended fixes

Restart your device

A restart clears temporary state that often causes transient errors.

Save your work and close open apps.
Restart the device from the power menu.
Reproduce the issue to check whether it persists.

Install Windows updates

Open Settings > Windows Update.
Click Check for updates and install everything available.
Restart if prompted.

Run System File Checker and DISM

Open Command Prompt as administrator.
Run sfc /scannow and let it complete.
Then run DISM /Online /Cleanup-Image /RestoreHealth.
Restart your PC.

Scan for malware (Windows)

Open Windows Security > Virus & threat protection.
Run a Full scan.
Quarantine or remove anything detected, then restart.

Contact Quickfix support

When to seek help

Seek extra help if the message keeps returning after reinstalling the app and updating Windows, or if multiple programs cannot start. That can point to a broader Windows file problem, a damaged installation, or security software repeatedly removing the file.

If you are not comfortable installing runtime components or running repair tools, ask a trusted technician or the app’s support team for help. Avoid downloading msvcp140.dll from random websites, since those copies can be unsafe or incorrect.
