Failed to load libmupdf.dll

When installed, SumatraPDF consists of 2 files:

  • SumatraPDF.exe
  • libmupdf.dll

You're reading this page because loading of libmupdf.dll failed and we can't proceed.

How can that happen?

There are many possible reasons.

Error code and error message is what Windows OS says the problem is.

To learn more about that specific error:

  • you can Google: LoadLibrary <error-code>
  • you can ask any AI: when calling LoadLibrary() win32 api I got an error <error code>. Tell me what it means

Or you can ask in SumatraPDF forums.
