an unhandled win32 exception occurred in w3wp.exe
提问by david.s
I get the following exception when trying to load an ASP.NET MVC website:
尝试加载 ASP.NET MVC 网站时出现以下异常：
Unhandled exception at 0x07070a91 in w3wp.exe: 0xC0000005: Access violation reading location 0x00000000.
w3wp.exe 中 0x07070a91 处的未处理异常：0xC0000005：访问冲突读取位置 0x00000000。
The Visual Studio Just-In-Time Debugger opens and the only information I can see in the debugger is this:
Visual Studio 即时调试器打开，我在调试器中看到的唯一信息是：
Call stack location:
msvbvm60.dll!06c00a91()
调用栈位置：
msvbvm60.dll!06c00a91()
The website uses some COM objects and everything worked fine until last week. This problem appeared out of the blue.
该网站使用了一些 COM 对象，直到上周一切正常。这个问题突然出现。
This is the error log from Windows Event Viewer:

Do you have any suggestions to help troubleshoot this problem?
您有什么建议可以帮助解决此问题吗？
Edit:I managed to solve the problem and now everything works. The solution involved tweaking some registry settings that the custom dlls need in order to function properly. So the problem didn't actually appear out of the blue, I just didn't realize some registry values were modified, which caused a com dll to crash.
编辑：我设法解决了问题，现在一切正常。该解决方案涉及调整自定义 dll 正常运行所需的一些注册表设置。所以这个问题实际上并不是突然出现的，我只是没有意识到一些注册表值被修改了，这导致了一个 com dll 崩溃。

You may start by capturing a crash dump when this issue happens again,
当此问题再次发生时，您可以先捕获故障转储，
http://support.microsoft.com/kb/2580960
http://support.microsoft.com/kb/2580960
Use Debug Diag 1.2 to set up a crash rule properly is step 1.
使用 Debug Diag 1.2 正确设置崩溃规则是第 1 步。
Once you have the dump, you can use WinDbg (part of Debugging Tools for Windows) to analyze it if you are familiar with dump analysis.
获得转储后，如果您熟悉转储分析，则可以使用 WinDbg（Windows 调试工具的一部分）对其进行分析。
If you are not capable of analyzing that, my suggestion is that you open a support case via http://support.microsoft.comand share the dumps with Microsoft support engineers.
如果您无法对此进行分析，我的建议是您通过http://support.microsoft.com打开一个支持案例并与 Microsoft 支持工程师共享转储。

My Solution is if you want to build it on 64bit:
我的解决方案是，如果您想在 64 位上构建它：
Debug ==> Options ==> Search for iis ==> enable using of 64bit Version of IIS Express
调试 ==> 选项 ==> 搜索 iis ==> 启用 64 位版本的 IIS Express
