解决方案

这实际上是通过与WiX的安装程序和DLL Storage.DataMovement的版本号的问题引起的。在升级过程中，Windows安装程序不会使用相同的文件的较低版本替换文件。什么happes是文件标记为删除，与下版本文件替换是不允许，然后该文件被删除（但不是替代）。

您可以通过两种方式解决这个问题：

（1）修复控制面板中的安​​装 - >卸载程序

（2）用较新的版本替换（0.8.5为例）。在最近的版本不应该显示这个问题。

解决方案

This is actually caused by an issue with the wix installer and the version number of the Storage.DataMovement dll. During an upgrade, the Windows Installer will not replace a file with a lower version of the same file. What happes is that the file is marked for deletion, the replacement with the lower version file is disallowed, and then the file is removed (but not replaced).

You can solve this in two ways:

(1) Repair the install in Control Panel -> Uninstall a program

(2) Replace with a more recent version (0.8.5, for example). The more recent versions should not display this issue
