NSIS调用卸载日志进行安全卸载

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)
 RMDir "$SMPROGRAMS$ICONS_GROUP"

#-- 根据 NSIS 脚本编辑规则,所有 Function 区段必须放置在 Section 区段之后编写,以避免安装程序出现未可预知的问题。--#
