registry - 无法通过 Inno Setup Installer 更改注册表项

Question

我想为专为 x64 Windows 10 设计的应用程序编写安装程序。我已在 Inno Setup Script 中定义:

[Setup]
MinVersion=10.0.14393
ArchitecturesAllowed=x64
ArchitecturesInstallIn64BitMode=x64
AlwaysRestart=yes

我还希望在安装过程中，在 Windows 注册表中启用长路径。我添加了以下代码:

[Registry]
Root: HKLM64; Subkey: "System\CurrentcontrolSet\Control\FileSystem"; ValueType: dword; ValueName: "LongPathsEnabled"; ValueData: "1"; Flags: createvalueifdoesntexist; Permissions: users-modify
Root: HKLM64; Subkey: "System\ControlSet001\Control\FileSystem"; ValueType: dword; ValueName: "LongPathsEnabled"; ValueData: "1"; Flags: createvalueifdoesntexist; Permissions: users-modify

当我在个人计算机上运行安装程序并重新启动时，注册表项会更改，但当我的同事运行安装程序并重新启动时，注册表项不会更改。该应用程序本身可以在我们的两台计算机上运行。我们都有 x64 Windows 10 系统和管理员权限。该脚本在某些计算机上失败的原因可能是什么？

计算机的日志文件内容，其中条目未更改:

只需删除 createvalueifdoesntexist flag .

这就是导致问题的原因，而您一开始就不希望出现这种情况。
