title: Create .exe with Pyinstaller ERROR: Assembly amd64_Microsoft.VC90.CRT_1fc8b3b9a1e18e3b_9.0.21022.8_none not found
body: <p>First I'll mention that I'm using Python 2.7.6 through the Anaconda distribution on Windows 7.</p>
  <p>When running <code>pyinstaller --onefile MyScripy.py</code> I am only getting one error which is the one mentioned in the title and the exe is created. When running the exe there are some issues using the ctypes library which I beleive are related to said error.</p>
  <p>I get this error a total of 12 times in the output from the pyinstaller command. Here is the complete output:</p>

  <p>It appears that Pyinstaller is looking for the windows .dlls it needs in the <code>C:\Users\Patrick\Anaconda\lib\site-packages\Pythonwin</code> directory, so I tried copying <code>msvcp90.dll</code> and <code>msvcm90.dll</code> there as per this question on SO <a href="https://stackoverflow.com/questions/23446124/solvedbundle-just-onefile">here</a>.</p>
  <p>But I still get the same errors. Additionally I also get the same errors when using the Pyinstaller command <code>pyinstaller --onedir MyScript.py</code> instead.</p>
  <p>Does anyone know how I can resolve this error?</p>
  <h1>Update</h1>
  <p>I ran the same pyinstaller command on my laptop at home and I do no get any errors whatsoever. Same python versions using Anaconda distribution on Windows 7. Without giving the full log, here is the section that contained the errors previously discussed:</p>

  <p>So basically on my laptop this is the directory where the <code>msvcr90.dll</code>, <code>msvcp90.dll</code>, and <code>msvcm90.dll</code> were found. I'll have to check out this directory on my computer at work and see what I can find.</p>
