Pyinstaller throwing massive amount of errors yet created executable works
<p>Take a look at this output from the console: <a href="http://pastebin.com/Vy5BqfYL" rel="nofollow">http://pastebin.com/Vy5BqfYL</a></p>

<p>My IDE is Pycharm and I'm using Pyinstaller with the single file executable. The PyInstaller is throwing massive amount of errors, yet the exe created seems to be working.</p>

<p>Using Python 3.5.</p>

<p>Should I be concerned?</p>

<p>Yes, you should be concerned because the binary will work for you but probably not in all targeted systems.</p>

<p>The 'errors' you are reporting are warnings and not errors. Pyinstaller tells you that it can't find windows CRT. However if the binary works for you: </p>

<ul>
<li><p><em>probably you have the CRT in some place which can not be found by PyInstaller</em>. Check dlls on your system (probably a file search can help). Check PATH environment var and PYTHONPATH.</p></li>
<li><p><em>probably you have some 32bit vs 64bit issue</em>: the python scripts uses a dll from one type while PyInstaller searches for another dll type which you have not... Check it! I saw in your trace that you are using a Windows 7 OS and PyInstaller is searching dlls in system32. Is your OS 64bit and your python version 32bit? This is some kind of dll smell.</p></li>
</ul>

<p><strong>To have a sane and good target binary you should ensure to have all dependencies. Do not rely on Windows updates on your target platforms but prefer packing all dependencies in a single distribution.</strong> </p>

<p>To ensure a software running in all platforms you should pack a binary for 32bit and one for 64bit. Or at least one for 32bits working also in a 64bit environment.</p>
