Support for Msvcp140.dll

Question

Need to place MSVCP140.dll in C:\Windows\System32 (for 64-bit) and C:\Windows\SysWOW64 (for 32-bit)

Reason: So that OBS (Open Broadcasting Software) installation can work properly. Currently says error code execution cannot complete because MSVCP140.dll not found

Answer 1

The Ai reply below is not fully correct, the Microsoft Visual C++ 2015–2022 Redistributable multi-installer is no longer available, and for the MSVCP140.dll error, you only need to install the 2015 version.

Click the link below, to download the Visual C++ 2015 redistributables.

Please Note, you must download and install both the x86 and x64 versions, do not try to install the ARM64 version:

Then, restart (not shut down) your PC to apply the changes.

Answer 2

Do not manually copy or place MSVCP140.dll into C:\Windows\System32 or C:\Windows\SysWOW64. The correct and supported way to fix the “MSVCP140.dll not found” error for OBS is to install or repair the appropriate Microsoft Visual C++ Redistributable package so Windows registers and services the DLL correctly.

For MSVCP140.dll (part of the Visual C++ 2015–2022 runtime), use these steps:

1. Install/repair the Visual C++ Redistributable
   • Download and run the current supported Visual C++ 2015–2022 Redistributable installers (both x64 and x86) from Microsoft.
   • Run each installer and choose Repair if already installed, or Install if not present.
   • This correctly places the runtime DLLs (including MSVCP140.dll) into the proper system locations and registers them.
2. Avoid copying DLLs by hand
   • Copying DLLs directly into System32 or SysWOW64 can:
     • Break side‑by‑side versioning (applications may expect a different build of MSVCP140.dll).
     • Be overwritten or removed by Windows servicing or updates.
   • Official guidance for missing VC++ runtime DLLs is to reinstall/repair the redistributable, not to copy individual DLLs.
3. If the error persists after repair
   • Uninstall all Visual C++ 2015–2022 Redistributable entries from Apps & Features.
   • Reinstall the latest supported 2015–2022 x64 and x86 redistributables.
   • Then reinstall OBS.

This approach ensures OBS and other applications that depend on MSVCP140.dll use the correct, supported runtime instead of an arbitrary copy.
