What does "entry point not found" mean?

The DLL was found, but it does not contain the function the program asked for. That means the file present is the wrong version, usually an older one, not that a file is missing.

How do I fix an entry point not found error?

Install the current version of the runtime package that owns the DLL, and remove any stray copy of that DLL sitting in the program folder, which takes priority over the correct system-wide one.

Missing DLL errors

“Entry point not found”

This is not a missing file. The DLL is right there, and it is the wrong version: the program asked it for a function that this particular build does not contain. That distinction changes the fix completely.

Why the difference matters

A missing DLL error means Windows could not find the file at all. An entry point error means it found it, loaded it, and then could not locate the specific function inside. The message usually names that function, which is why it looks so cryptic.

So the file you have is older than the program expects. Downloading another copy from a search result is the worst possible response here: you would be replacing a wrong-version file with another wrong-version file, from a source that cannot be verified, while the actual cause goes untouched.

How to fix it

01Read the error carefully. It names both the DLL and the function, and the DLL name tells you which package owns it.
02Look in the program's own folder for a copy of that DLL. Windows loads the one next to the executable before the system-wide one, so a stale copy there silently wins. Renaming it to .bak and relaunching is the fastest test.
03Install the current version of the runtime that owns the file. For anything named vcruntime or msvcp, that is the Visual C++ 2015-2022 Redistributable.
04If the DLL belongs to Windows itself, run sfc /scannow and then DISM, and make sure Windows Update has finished.
05If the error appeared after a program update, repair or reinstall that program: it may have shipped its own copy and failed to update it.

The stray copy in the program folder

This is by far the most common cause and the least known. Applications sometimes ship a runtime DLL next to their executable, and Windows always prefers that copy over the correct system-wide one. When the application is later updated but the bundled DLL is not, you get an entry point error on a machine where the right file is already installed.

Find the package that owns your file

Look up the DLL named in your error to see which runtime contains it, with the publisher's download URL and its SHA-256.
