1、在普通安装脚本前添加库
!include "LogicLib.nsh"
2、; 激活安装日志记录,该日志文件将会作为卸载文件的依据(注意,本区段必须放置在所有区段之前)
Section "-LogSetOn"
LogSet on
SectionEnd
3、
/******************************
* 以下是安装程序的卸载部分 *

; 根据安装日志卸载文件的调用宏
!macro DelFileByLog LogFile
ifFileExists `${LogFile}` 0 +4
Push `${LogFile}`
Call un.DelFileByLog
Delete `${LogFile}`
!macroend
Section Uninstall
!insertmacro MUI_STARTMENU_GETFOLDER "Application" $ICONS_GROUP
Delete "$INSTDIR${PRODUCT_NAME}.url"
; 调用宏只根据安装日志卸载安装程序自己安装过的文件
!insertmacro DelFileByLog "$INSTDIRinstall.log"
; 清除安装程序创建的且在卸载时可能为空的子目录,对于递归添加的文件目录,请由最内层的子目录开始清除(注意,不要带 /r 参数,否则会失去 DelFileByLog 的意义)
