<p style="margin-top:0;margin-bottom:0">It's not clear for me how you have build the CoinMp.dll, for example if build with visual studio you might also have to deploy the correct version of the c runtime (the same as the used for building the dll). If that
doesn't help then you can also detect all dependencies <span style="font-size: 12pt;">on windows machines using </span><a href="http://www.dependencywalker.com/" class="OWAAutoLink" id="LPlnk681166" previewremoved="true" style="font-size: 12pt;">http://www.dependencywalker.com/</a></p>

<p class="x_MsoNormal">Hello,</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">I am using the CoinMP.dll file compiled for windows in a python application. I use the ctypes library to load the dll as follows:</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal"><span style="font-family:Consolas">ctypes.cdll.LoadLibrary(CoinMP.dll)</span></p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">The application is frozen into a executable file using PyInstaller. It woks just fine in most computers, but some users got an error when loading the dll:</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal"><span style="font-family:Consolas">OSError: [WinError 126] The specified module could not be found</span></p>
<p class="x_MsoNormal"><span style="font-family:Consolas"> </span></p>
<p class="x_MsoNormal">I made sure the path provided to the loader is an absolute path, handled by the os.path library, and the CoinMP.dll is in the location. It seems the problem is that some .dll dependencies to load CoinMP.dll are not present in the user’s
machine.</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">Would it be possible to obtain a complete list of all the dependencies necessary to load CoinMP.dll?</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">Many thanks,</p>
