目标文件夹中的路径附加到旧路径，而不是使用 NSIS 显示新路径

Question

我安装的时候，目标文件夹默认显示路径“C:\Program Files (x86)\DllTesting\”（符合预期）。

enter image description here

然后我尝试将路径更改为“C:\Program Files\AppTest”

但是当我选择上面的路径并点击“确定”后，浏览器显示 “C:\Program Files\AppTest\DllTesting”而不是“C:\Program Files\AppTest”

enter image description here 当我从下面的路径中删除“DllTesting”时，它会正确显示新路径而不附加到旧路径。

安装目录 $PROGRAMFILES\DllTesting

但是我不能从上面的路径中删除“DllTesting”，因为默认情况下我应该显示路径 “C:\Program Files (x86)\DllTesting\”

下面是我的代码片段：

; DllTesting.nsi
;
;--------------------------------
!include LogicLib.nsh

Name "DllTesting"
OutFile "DllTesting.exe"

InstallDir $PROGRAMFILES\DllTesting

InstallDirRegKey HKLM "Software\NSIS_DllTesting" "Install_Dir"

RequestExecutionLevel admin

; Pages

Page components
Page directory
Page instfiles

UninstPage uninstConfirm
UninstPage instfiles

;--------------------------------

; The stuff to install
Section "DllTesting (required)"

  SetOutPath $INSTDIR
  
  ; Write the installation path into the registry
  WriteRegStr HKLM SOFTWARE\NSIS_DllTesting "Install_Dir" "$INSTDIR"

  ; Write the uninstall keys for Windows
  WriteRegStr HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\DllTesting" "DisplayName" "NSIS DllTesting"
  WriteRegStr HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\DllTesting" "UninstallString" '"$INSTDIR\uninstall.exe"'
  WriteRegDWORD HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\DllTesting" "NoModify" 1
  WriteRegDWORD HKLM "Software\Microsoft\Windows\CurrentVersion\Uninstall\DllTesting" "NoRepair" 1
  WriteUninstaller "uninstall.exe"

请帮我如何从浏览更改路径而不附加到以前的路径？

Answer 1

阅读文档中的 InstallDir，您会发现：

Note that the part of this string following the last \ will be used if the user selects 'browse', and may be appended back on to the string at install time (to disable this, end the directory with a \ (which will require the entire parameter to be enclosed with quotes).

尝试改变

InstallDir $PROGRAMFILES\DllTesting

到

InstallDir "$PROGRAMFILES\DllTesting\"

目标文件夹中的路径附加到旧路径，而不是使用 NSIS 显示新路径

Path in the Destination folder is appending to the old path instead of showing the new path using NSIS
