Qt platform plugin "windows" is not found on one computer
<p>I have an application built with Qt 5.5, deployed and running on x86 Windows 7 with dynamic linking. When I try to launch it <em>on that particular computer</em>, I get the following error:</p>

<blockquote>
  <p>This application failed to start because it could not find or load the
  Qt platform plugin "windows".</p>
  
  <p>Available platform plugins are: minimal, offscreen, windows, windows.</p>
  
  <p>Reinstalling the application may fix the problem.</p>
</blockquote>

<p>The "windows" plugin is indeed repeated twice in the list.</p>

<p>Though I have the libraries set up properly, such that they run without an issue on my main computer, here, the <code>platforms</code> directory doesn't seem to be found.</p>

<p>File list:</p>

<pre><code>MyProject\platforms\qwindows.dll
MyProject\Qt5Core.dll
MyProject\Qt5Cored.dll
MyProject\Qt5Gui.dll
MyProject\Qt5Guid.dll
MyProject\Qt5Widgets.dll
MyProject\Qt5Widgetsd.dll
MyProject\MyProject.exe
</code></pre>

<p>Many similar questions can be found about this error, but I have tried all the answers I have found about it (including changing file and folder names, adding various extra Qt libraries to the directory, etc.) without success. I have built the application again while making sure that all components have the right architecture, again without success.</p>

<p><em>Other than static linking, how can I make it run?</em></p>
