使用WiX自定义操作在安装文件夹中创建文件 [英] Create file in installation folder using WiX custom action

问题描述

我尝试创建一个 wix 安装程序，安装后需要在程序文件夹中创建文件。为此，我创建了一个自定义操作，但是现在遇到以下问题：

I try to create a wix installer that has the need to create a file in the programme folder after Installation. For doing so, I have created a custom action, but I now have the following problem:

要写入文件，我需要从 session [ INSTALLDIR] ，仅在执行操作立即 时可用。

In order to write the file, I need to know the installation directory from session["INSTALLDIR"], which is only available if the action is executed "immediate".

但是，如果我在安装文件之后运行立即，则目标目录尚不存在。如果我运行 deferred，则它存在，但是我无法访问 session [ INSTALLDIR] 。

However, if i run "immediate" after "install files", the target directory does not yet exist. If I run "deferred", it exists, but i cannot access session["INSTALLDIR"].

如果我在 InstallFinalize之后运行 immediate，我可以获取变量并且目录存在，但是我没有被提升，因此不允许写该文件。

If I run "immediate" after "InstallFinalize", I can get the variable and the directory exists, but I am not elevated and hence not allowed to write the file.

什么将文件写入安装目录的正确组合是什么？

What is the correct combination for writing a file to the installation directory?
