OPC not able to load file or assembly
<p>I am working on a C# application that interfaces with a Siemens OPC Server housed on the same PC. I've tested the server with OPC Scout as well as the Kepware QuickClient for communication problems, and they both work fine.</p>

<p>When I try to connect to my software, however, it comes back with an error that happens on the .Connect() command:</p>

<blockquote>
  <p>Could not load file or assembly 'OpcComRcw, Version 2.0.105.1,
  Culture=neutral</p>
</blockquote>

<p>There is another PC on a different site I have tested the software on, and it appears to connect with no problems. Any ideas as to what would cause the program to throw this error?</p>
