blocks|key|1838644|text|异常可能非常令人困惑，因为UCMA项目不需要对此SIPEPS+DLL进行显式引用，而且即使您找到DLL并将其移动到与应用程序相同的目录中，通常也会得到异常。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|1838645|结果发现，这通常是由两种原因之一引起的：|1838646|您针对的是.NET框架的错误版本。|ordered-list-item|1838647|你瞄准了错误的CPU类型。|1838648|在Visual中打开项目的属性，并确保选中了.NET+Framework4.5。|1838649|如果您没有运行Visual+2012，那么您有一个更大的问题，|blockquote|1838650|因为您不能在Visual+2010和更高版本中使用.NET+4.5。如果选择了框架的早期版本，请更改它，重新构建项目，然后再试一次。UCMA4.0将.NET+4.5列为需求。|1838651|如果你还有例外，|1838652|检查目标平台，并确保它是、任何CPU、或x64，用于所有项目。|1838653|自3.0版本以来，UCMA只在64位计算机上工作，有时项目会被无意中设置为x86，因此将尝试在启动时加载32位版本的SIPEPS.dll。好吧，没有32位版本的SIPEPS.dll，因此出现了一些误导性的例外。|1838654|参考文献|1838655|entityMap|0|LINK|mutability|MUTABLE|url|http://blog.greenl.ee/2012/08/21/error-sipeps-dll-ucma-4-0/^0|O|A|0|0|0|0|0|0|0|0|C|7|K|3|0|9|4|0|0|4|0|0^^$0|@$1|2|3|4|5|6|7|19|8|@$9|1A|A|1B|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|1C|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|1D|8|@]|D|@]|E|$]]|$1|K|3|L|5|J|7|1E|8|@]|D|@]|E|$]]|$1|M|3|N|5|6|7|1F|8|@]|D|@]|E|$]]|$1|O|3|P|5|Q|7|1G|8|@]|D|@]|E|$]]|$1|R|3|S|5|6|7|1H|8|@]|D|@]|E|$]]|$1|T|3|U|5|6|7|1I|8|@]|D|@]|E|$]]|$1|V|3|W|5|Q|7|1J|8|@$9|1K|A|1L|B|C]|$9|1M|A|1N|B|C]]|D|@]|E|$]]|$1|X|3|Y|5|6|7|1O|8|@$9|1P|A|1Q|B|C]]|D|@]|E|$]]|$1|Z|3|10|5|6|7|1R|8|@]|D|@$9|1S|A|1T|1|1U]]|E|$]]|$1|11|3|-4|5|6|7|1V|8|@]|D|@]|E|$]]]|12|$13|$5|14|15|16|E|$17|18]]]]

The exception can be very bewildering because UCMA projects don’t require an explicit reference to this SIPEPS DLL, and often you’ll get the exception even if you locate the DLL and move it into the same directory as your application. 

It turns out that it’s usually caused by one of two things:

<ol>
<li>You’ve targeted the wrong version of the .NET Framework.</li>
<li>You’ve targeted the wrong type of CPU.</li>
</ol>

Open up the properties for your project in Visual Studio and make sure .NET Framework 4.5 is selected. 

<blockquote>
 If you’re not running Visual Studio 2012, you have a somewhat larger
 problem,
</blockquote>

because you can’t use .NET 4.5 with Visual Studio 2010 and earlier.
If you had an earlier version of the framework selected, change it, rebuild the project, and try again. UCMA 4.0 lists .NET 4.5 as a requirement.

If you’re still getting the exception,

<blockquote>
 check the target platform and make sure it is Any CPU or x64 for all
 projects.
</blockquote>

UCMA has only worked on 64-bit machines since the 3.0 version, and what sometimes happens is that a project will get inadvertently set to x86, and will therefore try to load a 32-bit version of SIPEPS.dll on startup. Well, there isn’t a 32-bit version of SIPEPS.dll; hence the somewhat misleading exception.

You may also get this error message if your application server is not properly configured for UCMA applications.

In particular this message appears if replication is failing. To review the state of replication run <code>get-csManagementStoreReplicationStatus</code> and ensure that the "UpToDate" field is true for your application server.

if recompile doesn't make your day any better ,maybe, you are missing UCMA API Runtime

runtime install requirements :

on the target/host machine you want to run it on (which is probably unrelated to any Lync/SKF territory) OR on the development machine with a recompile to fit the downgrade/upgrade

blocks|key|1838717|text|除了这个伟大的答案。注意，您必须在调试模式和发布模式下将平台更改为x64。在不同的模式下，平台可以是不同的。我在VS2015和UCMA4，.net4.5有过这样的问题。在调试模式下，我的应用程序工作得很好，但是在发布构建后，它会出现异常失败，“无法加载文件或程序集SIPEPS”。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1838718|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

In addition to the great answer of tharif. Notice that you must change platform to x64 in debug mode and in release mode as well. Platforms can be different in different modes. I had such issue in VS2015 with UCMA4, .net4.5. In debug mode my application works great, but after release build it fails with exception 'Could not load file or assembly SIPEPS'.

I had developed an UCMA 4.0 application on both VS 2013 and VS 2010. When run project, I got this error:

<blockquote>
 Could not load file or assembly 'SIPEPS, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
</blockquote>

I used <code>.NET</code> 4 and had set target build platform to <code>x64</code>. Checked by <a href="http://www.dependencywalker.com/" rel="noreferrer">dependwalker_x64</a> and no file is missing.

I also used the App.config file from Sample but not work so I had changed the App.config file as follow:

<pre><code>&lt;runtime&gt;
&lt;assemblyBinding&gt;
 &lt;dependentAssembly&gt;
 &lt;assemblyIdentity name="SIPEPS" publicKeyToken="31bf3856ad364e35" culture="neutral"/&gt;
 &lt;bindingRedirect oldVersion="0.0.0.0-4.5.0.0" newVersion="5.0.0.0"/&gt;
 &lt;/dependentAssembly&gt;
&lt;/assemblyBinding&gt;
</code></pre>



How should I do for this problem? Thanks so much for any help!
