Hi everyone, I’m London. I mainly work with DLL files in a Windows 10 environment for a couple of in-house desktop applications built in C# and some older C++ tools that rely on third-party libraries. Recently Slither io, I’ve been encountering a recurring error where the application fails to start due to a missing VCRUNTIME140.dll, despite having installed Visual C++ Redistributables and other programs running fine. Reinstalling the redistributable package fixes the issue temporarily, but it returns after some updates or system restarts. Has anyone else experienced this kind of persistent DLL error, and is there a more permanent way to diagnose what’s actually removing or breaking the DLL reference?

Hi London,

Yes, I’ve seen this happen before with VCRUNTIME140.dll, especially in mixed C# / legacy C++ environments.

Firstly, make sure you're installing both the x86 and x64 versions of the Visual C++ Redistributable. Even on a 64-bit system, 32-bit apps require the x86 runtime.

Hi,

Yes, I’ve seen similar behavior before, and in many cases it’s not that the DLL is “missing” but that the wrong version (or architecture ) is being referenced.

Is this happening to multiple applications or just one specific build?
