COMException如何修复错误80040154？ [英] How to repair COMException error 80040154?

问题描述

将工作的C＃项目从64位Windows 7机器移动到32位XP机器，导致以下错误：

检索由于以下
错误：80040154，因此CLSID
{681EF637-F129-4AE9-94BB-618937E3F6B6}的组件的COM类工厂失败。

681EF637-F129-4AE9-94BB-618937E3F6B6不在注册表中，因此未正确安装，但这是以前在64位Windows 7机器上出现问题的相同ID。发现64位Windows 7机器上的此错误的解决方案 here （将Platform Target更改为x86），但这并不能解决32位XP机器上的问题。如何找到与681EF637-F129-4AE9-94BB-618937E3F6B6相关联的DLL，或者甚至更好地修复此异常？

解决方案

要查找DLL，请转到您的64位计算机并打开注册表。找到名为 HKEY_CLASSES_ROOT\CLSID\ {681EF637-F129-4AE9-94BB-618937E3F6B6} \InprocServer32 的密钥。该键将具有DLL的文件名作为其默认值。

如果您通过重新编译x86的项目来解决64位机器上的问题，需要查看注册表的32位部分，而不是在正常的位置。这是 HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\CLSID\ {681EF637-F129-4AE9-94BB-618937E3F6B6} \InprocServer32 。

如果DLL是为32位构建的，那么可以直接在32位机器上使用。如果它是为64位构建的，那么您必须联系供应商并从中获取32位版本。

当您有DLL时，通过运行c：\windows\system32\regsvr32.exe。

Moving a working C# project from a 64 bit windows 7 machine to a 32 bit XP machine caused the following error:

Retrieving the COM class factory for component with CLSID {681EF637-F129-4AE9-94BB-618937E3F6B6} failed due to the following error: 80040154.

681EF637-F129-4AE9-94BB-618937E3F6B6 is not in the registry so it is not properly installed, but this is same ID that was previously a problem on the 64 bit windows 7 machine. The solution to this error on the 64 bit windows 7 machine was found here (change Platform Target to x86) but this does not solve the problem on the 32 bit XP machine. How do I find the dll associated with 681EF637-F129-4AE9-94BB-618937E3F6B6, or, even better, how do I repair this exception?

解决方案

To find the DLL, go to your 64-bit machine and open the registry. Find the key called HKEY_CLASSES_ROOT\CLSID\{681EF637-F129-4AE9-94BB-618937E3F6B6}\InprocServer32. This key will have the filename of the DLL as its default value.

If you solved the problem on your 64-bit machine by recompiling your project for x86, then you'll need to look in the 32-bit portion of the registry instead of in the normal place. This is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\CLSID\{681EF637-F129-4AE9-94BB-618937E3F6B6}\InprocServer32.

If the DLL is built for 32 bits then you can use it directly on your 32-bit machine. If it's built for 64 bits then you'll have to contact the vendor and get a 32-bit version from them.

When you have the DLL, register it by running c:\windows\system32\regsvr32.exe.
