Inno Setup:删除另一个程序遗留的有问题的注册表项 [英] Inno Setup: Removing a problematic registry key left by another program

问题描述

我正在Inno Setup中为我的程序编写安装程序.我的程序使用网页和Internet Explorer与之交互.

I'm writing an installer for my program in Inno Setup. My program uses web pages and Internet Explorer to interact with it.

我的某些查询花费的时间超过10秒，我在朋友计算机上注意到他的Internet Explorer注册表项"RequestTimeout"将超时设置为10秒.此密钥不是Internet Explorer上自然存在的，它显然是由第三方安装程序添加的.但是，根据我在网上阅读的内容，很多人最终都使用了它.

Some of my queries take longer than 10 seconds, and I noticed on my friends computer that he had a registry key "RequestTimeout" for Internet Explorer that set a timeout of 10 seconds. This key is not naturally present on Internet Explorer, it is apparently added by a third party installer. But from what I read on the web quite a few people end up with it.

我的问题是，如果安装过程中存在此密钥，我可以告诉Inno Setup删除或修改此密钥吗?

My question is, can I tell Inno Setup to delete or modify this key if it is present during setup?

我已经搜索了所有关于Inno Setup和注册表项的资源，这些都与卸载选项有关.

I've googled and all the resources I could find about Inno Setup and Registry Keys have to do with uninstall options.

推荐答案

忽略有关是否应删除非"yours"值的要点，可以在安装时通过将类型设置为并添加deletevalue标志:

Ignoring the points about whether you should delete a value that's not "yours", you can easily delete a registry value at install time by setting the type to none and add the deletevalue flag:

[Registry]
Root: HKLM; Subkey: "Software\My Company\My Program\Settings"; ValueName: "Value"; ValueType: none; Flags: deletevalue;

您还可以添加Check:参数和其他条件语句.

You can also add a Check: parameter and other conditional statements.
