在IIS7.5的64位Windows上运行x86 Asp.net应用程序的问题

问题描述：

我目前正在准备一台运行我们的ASP.Net平台的新服务器。我第一次在64位Windows（2008 R2）上进行安装，并在IIS7.5上进行安装（在此之前总是7.0）。我们的网站是用x86构建的，所以我已经启用了应用程序池来使用32位应用程序。在IIS7.5的64位Windows上运行x86 Asp.net应用程序的问题

我被困在下面的错误，我得到的，当我浏览网站：

Server Error in '/' Application.

我用fuslogvw追查任何.NET绑定错误：4个组件出现了，但我得到我们的常规服务器上第一次浏览该网站时也是如此。程序集是CppCodeProvider，VJSharpCodeProvider和我们的两个* .resources文件。我研究过这些，我不认为它们是造成这个问题的原因，当然在找到工作环境后fuslogvw中缺少相同的程序集。

接下来我用Dependency Walker来研究网站的主DLL。似乎什么都不缺，但我得到了以下信息：

* Error: Modules with different CPU types were found.

我不认为这是一个问题，也是因为我的.NET程序集是x86和其他所有依赖是64位。

所以我真的很想知道什么缺少“模块”ASP.Net抱怨。

可能有人与编辑权限给了这个问题一个更好的标题？像“ASP.NET应用程序中的CppCodeProvider和VJSharpCodeProvider绑定错误” – mhenry1384 2010-01-04 22:41:40

这解决了我的问题：我必须将msvcr71.dll放在c：\ windows \ system32和c：\ windows \ syswow64中。

很高兴你钉上了它。不要忘记将此标记为帮助他人的答案。是什么让你看到那个？ – serialhobbyist 2009-11-05 20:49:39

一位同事记得他必须在旧设备上做同样的事情。不知道他是如何发现这一点的，但我尝试了它，并发挥了作用！ – 2009-11-06 07:53:08

尝试过并且不适合我。:( – 2014-05-24 11:56:01

在R2上放置4.0 beta 1应用程序时，最近有类似的问题，结果相似。我花了很长时间才发现问题是项目中引用的核心.net程序集（来自GAC）已被标记为CopyLocal true。我不知道如何 - 我当然没有故意去做，也没有其他人在做这件事。一旦我设置了它（并且，我认为我必须删除本地副本），一切都很好。

我会检查出来，谢谢+1 – 2009-11-05 10:39:56

我已经检查了这个，这可能不是这种情况... 所有System。*程序集来自GAC，我已经用fuslogvw检查了每一个绑定。 – 2009-11-05 12:00:18

我找到了答案我的问题与CppCodeProvider这里： http://www.experts-exchange.com/Programming/Languages/.NET/.NET_Framework_2.0/Q_24367712.html （需要登录）

关闭“定义TRACE常数”，否则计算机的问题上安装.NET SDK。

我解决了设置问题启用到真下的应用程序池的高级设置选项卡中的32位程序。

谢谢！这解决了我的问题。 – 2015-04-24 21:56:35
