如何检查软件安装文件夹并在 NSIS 的同一路径中进行静默更新

Question

我们有 .Net WPF 应用程序，当更新可用 NSIS 时，它会自行更新。但是现在 NSIS 直接在 ProgramFiles 中安装软件，即使该软件已经安装在其他路径中。 如何让它安装在与以前版本相同的路径中。

InstallDirRegKey 将在调用.onInit 之前从指定的注册表值读取并使用读取路径（覆盖InstallDir 属性）初始化$InstDir，但您必须自己将此注册表值写入您的@ 之一987654325@s.

你还没有发布你所有的代码，所以很难说到底发生了什么，但你似乎出于某种原因在使用 MultiUser，它有自己的定义，你需要设置：MULTIUSER_INSTALLMODE_INSTDIR、MULTIUSER_INSTALLMODE_INSTDIR_REGISTRY_KEY 和MULTIUSER_INSTALLMODE_INSTDIR_REGISTRY_VALUENAME.

Section
!ifdef MULTIUSER_INSTALLMODE_INSTDIR_REGISTRY_KEY & MULTIUSER_INSTALLMODE_INSTDIR_REGISTRY_VALUENAME
  ${If} $MultiUser.InstallMode == CurrentUser
    WriteRegStr HKCU "${MULTIUSER_INSTALLMODE_INSTDIR_REGISTRY_KEY}" "${MULTIUSER_INSTALLMODE_INSTDIR_REGISTRY_VALUENAME}" "$InstDir"
  ${Else}
    WriteRegStr HKLM "${MULTIUSER_INSTALLMODE_INSTDIR_REGISTRY_KEY}" "${MULTIUSER_INSTALLMODE_INSTDIR_REGISTRY_VALUENAME}" "$InstDir"
  ${EndIf}
!else
  WriteRegStr HK?? Software\?? ?? "$InstDir" ; Must match key used in InstallDirRegKey
!endif
