Inno Setup:安装更新时不要覆盖设置文件 [英] Inno Setup: Do not overwrite settings file, when installing an update

问题描述

我为C ++应用程序创建了一个Inno Setup脚本.该脚本可以正常运行，并且包含以下内容:

I have created an Inno Setup script for a C++ app. The script works fine and consists of the following:

[Files]
Source: "C:\Users\john\Desktop\My_App_setup\my_app.exe"; DestDir: "{app}"; \
    Flags: ignoreversion
Source: "C:\Users\john\Desktop\My_App_setup\settings\*"; DestDir: "{app}\settings"; \
    Flags: ignoreversion recursesubdirs createallsubdirs

文件是C ++可执行文件my_app.exe和由最终用户定制的设置文本文件.

The files are the C++ executable my_app.exe and a settings text file that is customized by the end user.

我想做的是，当我有一个新版本的my_app.exe来仅更新此文件并保留与用户迄今为止可能已更改的设置相同的设置.

What I'd like to do is when I have an new version of my_app.exe to update just this file and leave the same settings that the user may have changed so far.

我应该尝试什么?

推荐答案

只需添加

Just add onlyifdoesntexist flag:

Source: "C:\Users\john\Desktop\My_App_setup\settings\*"; DestDir: "{app}\settings"; \
    Flags: ignoreversion recursesubdirs createallsubdirs onlyifdoesntexist
