VSS到TFS错误：检索COM类工厂错误：8007007e

Question

我正在尝试使用VSS升级工具运行增量迁移。我正在通过命令提示符进行迁移。

我过去已成功将所有项目和历史迁移到TFS，我还检查了增量迁移。但是，现在我第三次这样做了，我得到了一个错误。

据我所知，一切都没有改变。关于我如何进行调试的任何一般提示都会有所帮助。

运行vssupgrade migrate settings.xml命令时出现的错误。

ERROR: Retrieving the COM class factory for component with CLSID {783CD4E4-9D54-11CF-B8EE-00608CC9A71F} failed due to the following error: 8007007e The specified module could not be found. (Exception from HRESULT: 0x8007007E)

查看分析工具创建的日志文件，错误如下所示：

Answer 1

COM interop fails when the convertor runs under x64，可能有效的技巧是从强制的32位命令提示符启动转换，您可以从以下命令开始：

c:\windows\SysWOW64\cmd.exe

这应该给你一个强制的32位上下文：

另一种选择是在任何时候改变corflags to force the convertor to x86：

corflags /32bit+ vssupgrade.exe

Answer 2

我的解决方案是修复Team Foundation Server的Visual Source Safe Upgrade工具。我从Microsoft's website重新下载了应用程序链接

然后运行并修复应用程序。这解决了我的问题。
