1. 症状

您的SharePoint 2010的服务器是不是最近一直出现这个错误呢？

Could not load file or assembly 'Microsoft.Office.InfoPath, Version=14.0.0.0' (...)

特别是当我们部署新的InfoPath解决方案时，我们突然之间发现，无法把模板上传到服务器当中去了，但是我们发现在GAC中，这个Microsoft.Office.InfoPath.dll 是存在的

问题出在哪里？

2.分析过程

在日志中有这么一句话:

System.IO.FileNotFoundException: Could not load file or assembly
'Microsoft.Office.InfoPath, Version=14.0.0.0, Culture=neutral,
PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system
cannot find the file specified.

根据前文分析，文件是一定存在的，但为什么呢，我们继续打开编译日志文件

报告如下:

现在我们找到原因了！好像是GAC的某个设置把14.00重定向到15.000，但是这个DLL又不支持SharePoint 2010，呵呵。

我们在运行当中打开如下的目录：

C:\Windows\assembly\GAC_MSIL

我发现如下的文件夹：Policy.14.0.Microsoft.Office.InfoPath 有一个子文件夹 “15.0.0.0__71e9bce111e9429c”.

我继续查看web.config文件中的设置，设置中有这么一段：

<?xml version="1.0" encoding="UTF-16"?>

<configuration>

	<runtime>

		<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

			<dependentAssembly>

				<assemblyIdentity publicKeyToken="71e9bce111e9429c" name="Microsoft.Office.InfoPath" culture="neutral"></assemblyIdentity>

				<bindingRedirect oldVersion="14.0.0.0" newVersion="15.0.0.0"></bindingRedirect>

			</dependentAssembly>

		</assemblyBinding>

	</runtime>

</configuration>

哈哈找到问题了！

3.解决方案

1. 打开“开始-运行” ，输入： C:\Windows\Assembly\GAC_MSIL

2.删除掉如下的文件夹：

Policy.14.0.Microsoft.Office.InfoPath
Policy.14.0.Microsoft.Office.InfoPath.Client.Internal.Host
Policy.14.0.Microsoft.Office.InfoPath.FormControl

3.  运行“ IISRESET /noforce” 重启IIS

哈哈哈，终于可以继续我的InfoPath的部署和开发拉！
