Problem running an executable missing qwtmathml.dll

  • Hello,

    I was provided an executable (exe) file that I am trying to run on Windows 8.1. When I run it says:

    The program can't start because qwtmathml.dll is missing from your computer. Try reinstalling the program to fix this problem.

    It came with Qwt 6.0.2 folder, so I first added that to my path and ran it like so:

    set PATH=C:\FilePath\Qwt-6.0.2\features;C:\FilePath\Qwt-6.0.2\libs;%PATH%

    This said the same thing about missing qwtmathml.dll, so I installed Qt and Qwt onto my computer afresh and tried the same thing, but qwtmathml.dll didn't seem to come with the fresh install. If I add it to the folder nothing changes.

    Can anyone give me an idea of something new to try to run this?

    The best thing would be to ask the people who gave you the executable to properly deploy the application or at least provide the missing dll. The reason why your attempts to solve the problem failed could be that the DLLs you tried to use were built using different compiler (different to the compiler used to build the executable).

    Hi and welcome to devnet,

    To add to @jsulm, did you build Qwt yourself ? If so, are you using the same setup as the people who provided the application ?
