About vcruntime140d_app.dll
vcruntime140d_app.dll is a DLL file (Dynamic Link Library) used by Windows programs to share code and resources. It allows multiple applications to use the same functions, improving performance and reducing redundancy.
Overview
vcruntime140d_app.dll is associated with the Microsoft Visual C++ Redistributable for Visual Studio 2017, and it's part of the Microsoft C Runtime Library. The "d" in the file name suggests that this is a debug version of the DLL, used for debugging purposes during application development rather than in release versions of applications distributed to end-users. The "app" likely indicates that this DLL is used for applications, possibly in the context of Universal Windows Platform (UWP) app development, which is supported by Visual Studio.In the development process, using debug versions of runtime libraries like vcruntime140d_app.dll allows developers to run their applications in an environment that's conducive to identifying bugs, as debug versions contain additional debugging information that is not present in release versions. This information can include more detailed error messages, the state of variables at the time of a crash, and other diagnostic information helpful for debugging.
If an application inadvertently requires the debug version of this DLL to run on a system that doesn't have Visual Studio 2017 installed, it might fail to start or operate correctly, showing errors related to the missing vcruntime140d_app.dll. This is because debug versions of Visual C++ DLLs are not distributed as part of the Visual C++ Redistributable packages and are typically only found on systems with Visual Studio installed.
To resolve issues related to missing debug DLLs like vcruntime140d_app.dll, developers should ensure that their applications are built in the release mode before distribution, which will link the application against the release versions of the necessary runtime libraries, included in the Visual C++ Redistributable for Visual Studio 2017. These redistributable packages are designed to be distributed with applications, ensuring that all the necessary runtime components are available on end-user systems.
File information is supported by Human Assisted Artificial Intelligence and should be used as a helpful tool. However, it is important to keep in mind that this information may not be up-to-date or entirely accurate.

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

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.

regsvr32 "C:\path\to\vcruntime140d_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\vcruntime140d_app.dll"
Or open Windows Terminal/PowerShell in the DLL’s folder and run:
regsvr32 vcruntime140d_app.dll
