The errors you may see
Windows may report:
- “The program can’t start because vcamp140_app.dll is missing from your computer.”
- “The code execution cannot proceed because vcamp140_app.dll was not found.”
- “There was a problem starting vcamp140_app.dll. The specified module could not be found.”
- “Error loading vcamp140_app.dll.”
- “vcamp140_app.dll is either not designed to run on Windows or it contains an error.”
The message can appear when starting a Store app, OneDrive, PowerToys, a game, an installer, or another application. “The specified module could not be found” can also mean that a dependency of vcamp140_app.dll is missing or incompatible.
The 60-second answer
vcamp140_app.dll is a genuine Microsoft C++ AMP runtime library. The _app form is associated with the Visual C++ runtime used by Universal Windows, Store, and other packaged applications, rather than being a normal standalone System32 file.

The safest fix is to identify the application showing the error, then repair or reinstall that application from Microsoft Store or its publisher. If the app uses a missing MSIX framework dependency, it may need the matching Microsoft.VCLibs.140.00 package. Do not download the DLL from a random website or copy it into System32.

What causes the error
The usual causes are:
- A damaged or missing Store/UWP framework package.
- An incomplete or corrupted application installation.
- An x86, x64, or ARM64 architecture mismatch.
- Antivirus quarantine or security software removal.
- Windows component corruption.
- A failed application, Windows, or Microsoft Store update.
A historical file listing shows a 32-bit 14.10.24605.0 build of approximately 0.36 MB. That is one recorded build, not a universal current specification. Other package versions and architectures exist.
Fix 1: Repair the affected app first
Start here if you know which program triggers the message.
- Press Windows + I to open Settings.
- Select Apps.
- Select Installed apps.
- Find the affected application.
- Select the three-dot menu beside it.
- Choose Advanced options.
- Select Repair.
- Start the application again.
Repair normally preserves app data. If the error remains:
Recommended Free Tools
- Return to the same Advanced options page.
- Select Reset.
- Confirm the reset.
- Start the app again.
Reset can remove the app’s local settings or stored data. If neither option works, uninstall the application and reinstall it from Microsoft Store or the publisher’s official installer.
For a game, open its launcher and use Verify, Repair, Scan and repair, or the equivalent option before reinstalling the entire game. This restores files from the game’s official distribution source rather than from a DLL mirror.
Update Microsoft Store and Windows
A Store framework can become inconsistent after an interrupted update.
- Open Microsoft Store.
- Select Library.
- Select Get updates.
- Allow available app updates to finish.
- Open Settings with Windows + I.
- Select Windows Update.
- Select Check for updates.
- Install available updates and restart Windows.
- Test the affected program again.
If the error began immediately after an update, repairing or reinstalling the affected app is generally safer than removing runtime packages manually.
Fix 2: Restore the matching VCLibs framework
Packaged apps can depend on Microsoft Visual C++ framework packages such as Microsoft.VCLibs.140.00 or Microsoft.VCLibs.140.00.UWPDesktop. The exact package and version are determined by the application’s manifest.
Do not manually edit protected C:Program FilesWindowsApps folders. Do not replace a package with an arbitrary APPX file.
For an enterprise or sideloaded MSIX application, obtain the dependency from the application vendor or deployment administrator. Microsoft documents an installation pattern like this:

Add-AppxPackage -Path .Microsoft.VCLibs.x64.14.00.Desktop.appx
Use the exact package supplied for the application. The filename above is only an example of the command pattern, not a universal download.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
If the dependency was installed through Microsoft Store, reinstalling the affected app normally restores its framework relationship. If the app is managed by an organization, contact the administrator rather than forcing a different architecture or package version.
Fix 3: Check x86, x64, and ARM64 compatibility
The correct runtime architecture follows the application, not simply the version of Windows.
- A 32-bit application needs x86 runtime components.
- A 64-bit application needs x64 components.
- An application running on an ARM device may require ARM64 dependencies or an appropriate emulation package.
A 32-bit app can run on 64-bit Windows, so installing only x64 components will not repair every missing-DLL error.
For a desktop program, check its documentation or executable properties. For an MSIX application, the package manifest identifies the processor architecture and framework dependencies. If the app was installed by a launcher, use that launcher’s repair or reinstall process so it selects the correct package.
Fix 4: Use the desktop Visual C++ Redistributable only when appropriate
The Microsoft Visual C++ Redistributable is intended primarily for conventional desktop applications. It is relevant when the error is actually for vcamp140.dll, or when the publisher explicitly says the desktop Visual C++ runtime is required.
Use Microsoft’s official downloads:
Install the architecture required by the failing desktop application. Multiple Visual C++ generations can coexist, so do not remove older versions merely because a newer one is present.
These packages may not restore vcamp140_app.dll, because the _app runtime is associated with packaged application frameworks. If the failing program is a Store app, return to app repair and framework recovery instead.
Fix 5: Check antivirus quarantine
If the program worked previously and the file disappeared suddenly, check your security software.
- Open Windows Security.
- Select Virus & threat protection.
- Select Protection history.
- Review recent quarantined or blocked items.
- Check whether the affected application or its package was involved.
- Run a current scan before restoring anything.
Restore a quarantined file only when it belongs to the expected Microsoft or application package location and the package can be verified or repaired from an official source. If the file came from an unofficial DLL site, do not restore it blindly. Remove the unofficial copy and reinstall the owning application.

Fix 6: Repair Windows components with DISM and SFC
Use these commands when several applications show system-file errors, Windows itself behaves incorrectly, or app repair has not helped.
- Open Start.
- Type
Command Prompt. - Right-click Command Prompt.
- Select Run as administrator.
- Run this command first:
DISM.exe /Online /Cleanup-image /Restorehealth
- Wait for it to complete.
- Then run:
sfc /scannow
- Restart Windows.
- Test the affected application.
DISM repairs the Windows component store, and SFC checks protected Windows system files. They may not reconstruct a private Store-app package, so reinstall the application if the error remains.
Free tools Windows power users keep installed
One-click scans. No signup required.
When repeated manual DISM and SFC runs make it difficult to see what changed, Outbyte PC Repair can scan for reported system problems and show what needs attention; its repair functions require the full version. It is optional, and reinstalling the affected app remains the definitive fix when that app owns the missing runtime.
Fix 7: Update graphics and chipset drivers when the app uses C++ AMP
C++ AMP supports data-parallel computation on hardware such as GPUs. A driver problem can therefore appear alongside an application runtime failure, although a driver update does not replace vcamp140_app.dll.
To check drivers through Windows:
- Right-click Start.
- Select Device Manager.
- Expand Display adapters.
- Right-click the graphics device.
- Select Update driver.
- Choose Search automatically for drivers.
- Repeat for relevant chipset or system devices.
- Restart Windows and test the application.
For the most reliable driver, use the computer manufacturer’s official support page or the graphics hardware manufacturer’s official software. Avoid replacing a working driver with an unrelated package.
When manually checking many hardware entries is impractical, Outbyte Driver Updater can scan for outdated drivers and identify available updates; installing drivers through the full version is optional. A driver update will not substitute for repairing the application package that owns vcamp140_app.dll.
Crashes, No Sound, or Screen Glitches?
Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteWindows Errors? Fix Them Before They Spread
Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallDo not use regsvr32 for this file
Do not register vcamp140_app.dll with regsvr32 as a routine fix. Runtime libraries are normally loaded by applications and are not generally COM or ActiveX components that expose the DllRegisterServer entry point required for registration.
regsvr32 is appropriate only when the software vendor specifically tells you to register a particular self-registering component. For this error, repair or reinstall the owning app instead.
Do not copy a downloaded DLL into System32
Manually copying a DLL into C:WindowsSystem32 or C:WindowsSysWOW64 is unsafe and often ineffective. The downloaded file may contain malware, use the wrong architecture, belong to another runtime build, or require other missing dependencies. It can also create version conflicts with Windows servicing.
A protected WindowsApps directory should not be edited manually. Use Microsoft Store, the application publisher, or the organization that deployed the MSIX package.
If nothing has worked
Identify the exact executable that produces the error rather than treating the filename as the owner.

- Select System Restore.
- Choose a restore point from before the failure.
- Review the affected programs.
- Complete the restore and test the application.

1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteFAQ
Is vcamp140_app.dll a Microsoft file?
Yes. It is part of Microsoft’s Visual C++ 14.x and C++ AMP runtime family. The file is normally delivered through an application or framework package, not as a standalone file for general copying.
Is it part of Windows?
It is not normally a standalone System32 component. A packaged application may place it inside a protected application or framework directory.
Is it part of Visual Studio?
Visual Studio can build software that uses the Visual C++ runtime, but the missing file usually needs to be restored for the application that is failing. Installing Visual Studio is not a general repair.
Does the normal Visual C++ 2015–2022 Redistributable fix it?
Not necessarily. That package is mainly for desktop runtime files. A Store or MSIX application may instead require the matching Microsoft.VCLibs.140.00 framework.
The Tool Desk
Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Why does the name end in _app?
The suffix distinguishes the app or packaged-application form of the runtime from the desktop vcamp140.dll family.
Should I download the DLL from a DLL website?
No. Use Microsoft Store, the application publisher’s official installer, or the framework package supplied by the application’s deployment source. A replacement file can be malicious, incompatible, or the wrong architecture.
What should I do if the error appeared after Windows Update?
Restart, install all pending Windows and Store updates, then repair or reinstall the affected app. If the problem continues, use DISM and SFC, and inspect Event Viewer and antivirus history.
Can the filename alone identify the program?
No. The same runtime can be used by different packaged applications. The affected app, file path, package manifest, and installation source are needed to identify the owner.
