Overview

What Is vcruntime140_1_app.dll?

vcruntime140_1_app.dll is a Microsoft Visual C++ runtime library that ships with Windows Store (UWP) and Desktop Bridge applications. It is part of the VC++ 2015–2022 AppX Runtime, which is packaged inside an application’s own installation directory rather than installed system-wide.

This DLL contains core C/C++ runtime functions needed by apps that were built with the Universal CRT and deployed through Microsoft’s packaged app technology.

It is not the same as:

  • vcruntime140.dll
  • vcruntime140_1.dll

Those belong to the standard VC++ Redistributable. vcruntime140_1_app.dll is specifically the AppX/UWP-scoped version.

On DLLme, all versions of this file are marked Verified, meaning they were obtained from legitimate, official Windows application packages.

What Does vcruntime140_1_app.dll Do?

This DLL provides the AppContainer-safe version of the Visual C++ runtime, including:

✔ Startup and Initialization Routines

  • CRT initialization
  • Thread setup
  • C++ object lifecycle hooks

✔ Standard C/C++ Runtime Support

  • Memory allocation (malloc, free)
  • String and buffer handling
  • Math utilities
  • Exception handling
  • File/stream functions allowed inside AppContainer sandboxes

✔ ABI Compatibility for UWP

Ensures that packaged apps built with modern MSVC toolchains work on:

  • Windows 10
  • Windows 11
  • Xbox app platform
  • Windows Store apps
  • Desktop applications packaged as .AppX or .MSIX

Where This DLL Comes From

You will find this DLL installed:

  • Inside a UWP or MSIX app folder
  • Inside WindowsApps directories, typically:
    • C:\Program Files\WindowsApps\AppName\
  • Alongside packaged runtime components for Store apps
  • In Desktop Bridge applications bundled via MSIX/AppX packaging

Unlike classic VC++ DLLs, this one is not installed globally.

Common Software That Uses This DLL

Any packaged application built with modern Visual Studio C++ tools may include it, such as:

  • Microsoft Store games
  • Windows Store utilities
  • UWP desktop apps
  • MSIX-packaged enterprise applications
  • Desktop apps published through the Store using Desktop Bridge

Since the DLL is isolated per-app, you may see multiple versions installed on the same PC, each belonging to a different Store/MSIX package.

Common Error Messages

“vcruntime140_1_app.dll is missing.”
“The code execution cannot proceed because vcruntime140_1_app.dll was not found.”
“Failed to load vcruntime140_1_app.dll.”

These errors happen when:

  • A Store/MSIX app installation becomes corrupted
  • The app folder was deleted or moved manually
  • Permissions on the WindowsApps folder are broken
  • An incomplete extraction of an MSIX package occurred
  • A necessary dependency within the package is missing

This DLL rarely causes system-level issues — the problem is almost always with the app’s package, not the OS.

Is vcruntime140_1_app.dll Safe?

Yes — when provided by:

  • The Microsoft Store
  • An MSIX/AppX application
  • Verified DLLme versions originating from real application packages
  • A legitimate software vendor

It becomes suspicious only if:

  • Found outside WindowsApps / packaged app folders
  • Downloaded from untrusted websites
  • Paired with unknown executables

How to Fix Issues With This DLL

✔ 1. Reinstall the Application

This is the most reliable fix. MSIX/AppX apps include their own matching VC runtime, including this DLL.

✔ 2. Repair or Reset the App (Windows Settings)

  1. Go to Settings → Apps → Installed Apps
  2. Choose the problematic app
  3. Select Advanced Options
  4. Click Repair or Reset

✔ 3. Update the App from Microsoft Store

If a dependency is outdated or corrupted, updating may restore the correct bundled runtime.

✔ 4. Avoid Copying the DLL Manually

Store/UWP runtimes are tightly controlled; mixing versions or copying DLLs across app folders usually breaks the package.

✔ 5. Check WindowsApps Folder Permissions

Incorrect permissions can cause DLL load failures.

Windows default permissions should not be modified manually.

Summary

  • vcruntime140_1_app.dll is the AppX/UWP version of the Visual C++ 2015–2022 runtime library.
  • Used exclusively by Windows Store apps and MSIX-packaged software.
  • Lives inside the application’s folder, not in System32/SysWOW64.
  • Errors usually mean the application package is damaged — reinstalling or repairing the app fixes it.
  • DLLme’s verified versions come from legitimate Microsoft Store packages.

Fixes and Solutions

The first step in resolving DLL errors is to completely uninstall the affected software and reinstall its latest version. We know this does not always solve the problem, which is why DLLme exists. If reinstalling the application does not help, or if you are unsure which app is causing the error, follow the steps below. These are the most common solutions for fixing vcruntime140_1_app.dll errors.

  • Repair Windows: Make sure Windows is fully updated, then open Windows Terminal or PowerShell as an administrator (search for “PowerShell” in the Start menu, right-click it, and choose “Run as administrator”). This allows you to repair the Windows component store and run the System File Checker (SFC).

    Repair the Windows component store so SFC can pull clean files:

    DISM /Online /Cleanup-Image /RestoreHealth

    Scan all protected system files and automatically repair problems:

    sfc /scannow
  • Uninstall & Reinstall: On this DLL page, check the Company/Product section to identify the related app, then fully uninstall it. If you plan to continue using it, reinstall the latest version. Be sure to save or back up any important data before uninstalling. Windows or antivirus software may sometimes quarantine DLL files, especially if the DLL is unfamiliar or appears suspicious. Check your antivirus quarantine or logs to determine if this is the cause of your issue.
  • Download the DLL: Download the latest 32-bit or 64-bit version of the DLL directly from our repository using the download button above. Most users will need the 64-bit version, but if you are unsure, or if a 64-bit version is not available, you can install both the 32-bit and 64-bit DLLs. DLLme verifies DLLs that come from our admins, partners, and trusted affiliates. User-uploaded files may be verified later if a trusted source is confirmed.
  • Register the DLL: Most DLL files do not need registration, but some DLLs are COM components and must be registered to work correctly. If registration is required, open Windows Terminal or PowerShell as an administrator.

    Register the DLL (you can also drag the DLL file into the window to automatically fill in its full path): 

    regsvr32 "C:\path\to\vcruntime140_1_app.dll"

    If you are registering a 32-bit DLL on 64-bit Windows, use the 32-bit RegSvr32: 

    C:\Windows\SysWOW64\regsvr32 "C:\path\to\vcruntime140_1_app.dll"

    Or open Windows Terminal/PowerShell in the DLL’s folder and run: 

    regsvr32 vcruntime140_1_app.dll

How to Install vcruntime140_1_app.dll

To install vcruntime140_1_app.dll, place the DLL file in the appropriate Windows system folder or in the same folder as the application’s .exe file. If you are not sure which version (32-bit or 64-bit) to use, you can safely install both.

On 64-bit versions of Windows, place 64-bit DLL files in:

C:\Windows\System32\vcruntime140_1_app.dll

Place 32-bit DLL files in:

C:\Windows\SysWOW64\vcruntime140_1_app.dll

Or place the DLL file next to the application’s .exe:

C:\path\to\exe\vcruntime140_1_app.dll
