Summary
That dreaded “msvcp140d.dll is missing” error can halt your work and games in an instant. This clear, step-by-step guide will walk you through proven msvcp140d.dll error fix methods, from a quick manual download to repairing the Microsoft Visual C++ Redistributable. Follow our instructions to resolve the frustration and get your Windows 10 or 11 PC running smoothly again.
Introducción: Qué es el error msvcp140d.dll y por qué ocurre en Windows 10/11
That sudden, stark alert—“The program can’t start because msvcp140d.dll is missing from your computer”—is a frustration familiar to many Windows users. It’s an interruption that can strike whether you’re launching a critical work application, a beloved game, or a new piece of software. But what exactly is this elusive file causing the commotion? In essence, the msvcp140d.dll is a Dynamic Link Library (DLL) file, a crucial component of the Microsoft Visual C++ 2015 Redistributable package. The ‘d’ in its name is particularly telling: it signifies this is a debug version. This means it’s primarily intended for software developers during the testing and debugging phase of their programs, not for general end-user distribution.
Crucially, if you encounter this error as a standard user, it often indicates that a program was accidentally shipped with a development build, or that your system lacks the necessary runtime components it expects to find.
The error’s appearance on Windows 10 and 11 isn’t a sign of a fundamentally broken operating system, but rather a mismatch in software dependencies. Your system may be missing the correct Visual C++ redistributable altogether, a conflicting older version might be present, or the required DLL file itself could have become corrupted or been deleted by overzealous security software. Understanding this distinction between a debug (msvcp140d.dll) and a release (msvcp140.dll) file is the first step towards an effective DLL error fix, steering you away from simply downloading any DLL file from the web—a practice fraught with risk—and towards more robust, systemic solutions.
Let’s now demystify the specific triggers and delve into the root causes behind this pesky alert, which will naturally guide us towards the permanent fixes outlined in the following sections.

Before we rush into solutions, it’s prudent to diagnose the ailment. Pinpointing the precise trigger for the msvcp140d.dll is missing error transforms a frustrating guessing game into a targeted repair operation. The root causes typically fall into a few distinct, yet sometimes interconnected, categories.
The most frequent culprit is the improper distribution of software. As highlighted previously, the ‘d’ denotes a debug version. If you’re encountering this error after installing a new application or game, it’s highly probable that the developer inadvertently included the debug DLL from their testing environment in the public release build. Your system, configured for standard use, lacks this specific file and the supporting debug runtime libraries. Another common scenario is a corrupted, missing, or incorrectly registered Microsoft Visual C++ 2015 Redistributable package. This essential framework provides the release versions of these DLLs; if it’s damaged or an older version conflicts with a newer one, applications can malfunction and erroneously call for debug files.
Beyond software issues, system integrity plays a role. Aggressive antivirus or disk cleanup utilities can sometimes quarantine or delete DLL files mistakenly identified as threats. Furthermore, underlying system file corruption—perhaps from an interrupted update or failing storage hardware—can destabilise core dependencies. While less common for this specific debug DLL, outdated or faulty device drivers, particularly for critical components, can create instability that manifests in various errors, including missing library alerts.
A useful diagnostic step: note when the error appears. Is it consistent for one specific program, or sporadic across several? This can immediately point towards an application-specific bug or a deeper system-wide issue.
Understanding these primary catalysts—faulty software packaging, a compromised Visual C++ installation, overzealous security tools, or systemic decay—provides the essential context for choosing the most effective msvcp140d.dll error fix. With the ‘why’ established, we can now proceed to the practical ‘how’, beginning with the most direct, though not always recommended, approach.
Método 1: Descargar e instalar el archivo msvcp140d.dll manualmente
Let’s address the most direct, and often first-thought, solution: manually obtaining the missing file. Given the error message explicitly names msvcp140d.dll, it’s tempting to search for a quick download msvcp140d.dll for Windows 10 or Windows 11. This method involves sourcing the specific DLL file and placing it in the correct directory, typically the application’s own folder or the system-wide C:\Windows\System32 (for 64-bit) or C:\Windows\SysWOW64 (for 32-bit applications on a 64-bit OS).
Proceed with extreme caution. Downloading DLLs from unofficial third-party websites is a significant security risk. These files can be outdated, incompatible, or maliciously bundled with malware. Microsoft does not host standalone DLL downloads for end-users.
If you choose this path, the only remotely safe source is the official Microsoft Visual Studio development tools, which is impractical for most. Furthermore, as established in our introduction, this debug DLL relies on other debug runtime libraries (vcruntime140d.dll, ucrtbased.dll, etc.). Installing msvcp140d.dll alone is like fitting one cog from a complex watch—without the rest of the mechanism, it simply won’t function. You’ll likely be met with a new error about a different missing debug component.
A slightly more robust manual approach is to re-register the existing file if it’s present but not properly recognised. You can open Command Prompt as Administrator and try:
regsvr32 msvcp140d.dll
However, this often fails for this particular DLL as it is not designed to be registered in this way.
In practice, this manual download method is a symptomatic fix at best and a security hazard at worst. It ignores the underlying cause—a missing or faulty Visual C++ Redistributable package—and fails to provide a stable foundation for your software. While it might feel like a swift remedy, it typically leads to further instability. For a lasting solution, we must look to repairing the system itself, which is precisely where our next method proves infinitely more reliable.
Método 2: Reparar Microsoft Visual C++ Redistributable
Having established the perils of a manual DLL download, we turn to a far more robust and systematic remedy: addressing the very framework the file belongs to. The most reliable msvcp140d.dll error fix often lies not in chasing a single component, but in repairing or reinstalling the entire Microsoft Visual C++ Redistributable package it depends upon. This approach tackles the root cause head-on, ensuring all necessary runtime libraries—both release and, crucially, the debug versions sometimes erroneously required—are correctly installed and configured on your system.
Your first action should be to visit the ‘Apps & features’ or ‘Programs and Features’ control panel. Search for any existing installations of “Microsoft Visual C++ 2015 Redistributable”. You will likely find both x86 and x64 versions. The goal here is not necessarily to remove them immediately, but to first attempt a repair. Many modern versions offer a built-in repair function via the ‘Modify’ button. Running this can resolve issues with corrupted registrations or missing files without a full reinstall.
If a simple repair proves insufficient, a clean reinstallation is the logical next step. Uninstall the 2015 Redistributable packages, then download the latest version directly from the official Microsoft website. It is vital to install both the x86 and x64 variants to cover all software dependencies. This process replaces the entire suite of libraries with a clean, official copy, effectively resetting that critical part of your system’s software foundation.
A pro tip: Before reinstalling, use a tool like the ‘Visual C++ Redistributable Runtimes All-in-One’ package from trusted tech community sources. This can neatly remove all existing versions, ensuring a truly clean slate for your fresh installation and preventing legacy conflicts.
This method elegantly solves the core dependency issue that manual DLL swapping ignores. By restoring the official Microsoft package, you provide a stable, secure, and complete runtime environment for your applications. Should the error persist even after this, it strongly suggests a deeper system-level corruption, which we must then investigate with more powerful tools.
Método 3: Ejecutar el comprobador de archivos de sistema (SFC y DISM)
When the previous methods—addressing the specific application’s dependencies or reinstalling the Visual C++ framework—fail to resolve the issue, the problem may stem from deeper within Windows itself. Corrupted or missing protected system files can undermine even the most correct software installations. This is where built-in Windows recovery tools, specifically the System File Checker (SFC) and the Deployment Image Servicing and Management (DISM) tool, become invaluable for a comprehensive DLL error fix.
Think of these utilities as your PC’s internal diagnostics and repair crew. The SFC /scannow command is the first line of defence. Executed from an Administrator Command Prompt or PowerShell, it scans all protected system files and replaces incorrect versions with genuine Microsoft copies from a cached directory. It’s a straightforward yet powerful tool for addressing generic system file corruption that could be affecting a wide range of components, not just DLLs.
However, SFC relies on a local cache that itself can become damaged. If SFC runs but cannot repair files, or if the error stubbornly persists, you must then employ the more robust DISM tool. DISM connects to Windows Update (or uses a known-good installation source) to fix the underlying Windows component store—the very source SFC draws its repairs from. Running DISM /Online /Cleanup-Image /RestoreHealth effectively repairs the system image, providing SFC with the healthy resources it needs to do its job properly.
Execution order matters: Always run SFC first for a direct scan. If it fails, then proceed with DISM to repair the source, followed by another SFC scan to complete the fix. This one-two punch is a proven strategy for tackling entrenched system file issues.
Here is a concise guide to the process:
1. Open Windows Terminal, Command Prompt, or PowerShell as Administrator.
2. To run SFC, type: sfc /scannow and press Enter. Allow the scan to complete (it can take 10-20 minutes).
3. If issues are found but cannot be fixed, or post-SFC problems remain, run DISM: DISM /Online /Cleanup-Image /RestoreHealth.
4. Once DISM finishes successfully, reboot your system and run sfc /scannow again to finalise repairs.
This method moves beyond application-specific fixes to fortify the core operating system, addressing corruption that could be the hidden culprit behind the missing DLL alert. If, after this thorough internal repair, the msvcp140d.dll error lingers, it’s time to examine whether your system’s ongoing updates and drivers are part of the puzzle.
Método 4: Actualizar Windows y controladores de dispositivo
A stubborn msvcp140d.dll error that withstands the previous system-level repairs can often be a symptom of a wider compatibility rift. Outdated system components or drivers create an unstable foundation upon which even perfectly installed software can falter. Pursuing a comprehensive update drivers to fix msvcp140d.dll error strategy, in tandem with ensuring Windows itself is current, addresses these latent incompatibilities that more targeted fixes might miss.
Begin with Windows Update. Navigate to Settings > Windows Update and select ‘Check for updates’. Install all available feature, quality, and optional updates. Microsoft routinely issues patches that resolve known compatibility issues with core frameworks like the Visual C++ runtimes. An up-to-date OS provides the most stable and secure platform, closing gaps that could cause applications to behave erratically or seek out incorrect library files.
Driver updates, however, are where precision matters. Focus on display and chipset drivers first, as they have the most direct interaction with application performance and system libraries. Avoid the temptation to use generic driver updater tools from unofficial sources. Instead, visit your hardware manufacturer’s website directly:
* For GPUs: NVIDIA, AMD, or Intel graphics support sites.
* For chipsets & others: Your PC or motherboard manufacturer’s support page (e.g., Dell, HP, Lenovo, ASUS, MSI).
Manually download and install the latest stable drivers recommended for your specific model and Windows version. This ensures optimal compatibility and can resolve obscure conflicts that manifest as DLL errors.
Why this works: Modern applications, especially games and professional software, rely heavily on direct communication with your hardware via drivers. An outdated or corrupt driver can misinterpret instructions, leading the software to fail in loading its required dependencies—sometimes throwing a misleading error about a missing debug DLL.
By systematically ensuring both your operating system and key drivers are current, you eliminate a common layer of environmental instability. This isn’t merely about patching a single error; it’s about cultivating a harmonious software ecosystem where such faults are less likely to arise in the first place. With your system now optimised and repaired, let’s turn our attention to the habits that will keep it running smoothly, steering clear of future DLL-related frustrations.
Prevención y mejores prácticas para evitar errores DLL en el futuro
Having navigated the immediate fixes, the true mark of a savvy user is shifting from reactive repair to proactive prevention. Cultivating a few sensible digital habits can dramatically reduce the likelihood of encountering not just the msvcp140d.dll error, but a whole host of similar system frustrations. Think of it less as a rigid set of rules and more as a philosophy for maintaining a clean, stable computing environment.
First and foremost, source your software wisely. The single most effective practice to avoid DLL errors is to download applications and games exclusively from official vendors, trusted digital storefronts like Steam or the Microsoft Store, or the developer’s own verified website. This minimises the risk of installing malformed packages that incorrectly bundle debug libraries intended for development builds. Secondly, adopt a disciplined approach to system maintenance. While Windows Update handles the OS, make a regular, manual check for driver updates—particularly for your graphics card and chipset—a quarterly calendar reminder. Rely on the hardware manufacturer’s own support pages, not third-party auto-updaters which can sometimes introduce their own conflicts.
Beyond installations, consider how you uninstall. Using the built-in ‘Apps & features’ settings is good; employing a dedicated uninstaller tool that cleans residual files and registry entries is often better, preventing “DLL hell” where leftover fragments from old programs interfere with new ones. Furthermore, exercise restraint with system cleaning utilities. While tempting, overzealous cleaners can mistakenly remove files deemed unnecessary but which are, in fact, critical dependencies.
A golden rule: before any major system change—a new software install, a driver update, or a Windows feature update—consider creating a system restore point. It’s a five-minute task that offers a priceless rollback option should anything go awry.
By embedding these best practices into your routine, you build resilience into your PC’s software ecosystem. You transition from constantly troubleshooting symptoms to enjoying a smoother, more reliable computing experience. While these steps won’t guarantee absolute immunity from every error, they will fortify your system against the most common triggers, leaving you better prepared for whatever comes next—including knowing when a problem has grown beyond a DIY fix.
