Inno Setup 6 内置了对non-administrative install mode 的支持。
基本上,你可以简单地设置PrivilegesRequiredOverridesAllowed:
[Setup]
PrivilegesRequiredOverridesAllowed=commandline dialog
此外,您可能希望使用常量的auto* 变体。尤其是{autopf} 的DefaultDirName。
[Setup]
DefaultDirName={pf}\My Program
以下是我的(现已过时的)Inno Setup 5 解决方案,基于 @TLama's answer。
当设置在非提升状态下启动时,它会请求提升,但有一些例外:
- 仅适用于 Windows Vista 和更新版本(尽管它也应该适用于 Windows XP)
- 升级时,安装程序将检查当前用户是否具有对先前安装位置的写入权限。如果用户具有写入权限,则安装程序不会请求提升。因此,如果用户之前已将应用程序安装到用户文件夹,则升级时不会请求提升。
如果用户在新安装时拒绝提升,安装程序将自动回退到“本地应用程序数据”文件夹。 IE。 C:\Users\standard\AppData\Local\AppName.
其他改进:
- 提升的实例不会再次要求语言
- 通过使用
PrivilegesRequired=none,安装程序将在提升时将卸载信息写入HKLM,而不是HKCU。
