Description
This code was written for Rookie12 a long while back. So many people have asked the same question since, so I thought that it was a good idea to put it up on here. You need the TrimNewLines function present in your script also. Make sure you rename the TrimNewLines function name to un.TrimNewLines (as the function is used in the uninstaller, ala "un.").
The Script
!define UninstLog "uninstall.log" Var UninstLog ; Add file macro !macro File FilePath FileName !define FileID ${__LINE__} IfFileExists "$OUTDIR\${FileName}" NoExtract_${FileID} File "${FilePath}${FileName}" NoExtract_${FileID}: FileWrite $UninstLog "$OUTDIR\${FileName}$\r$\n" !undef FileID !macroend !define File "!insertmacro File" ; Set output path macro !macro SetOutPath Path SetOutPath "${Path}" FileWrite $UninstLog "${PATH}$\r$\n" !macroend !define SetOutPath "!insertmacro SetOutPath" Section -openlogfile IfFileExists "$INSTDIR\${UninstLog}" +3 FileOpen $UninstLog "$INSTDIR\${UninstLog}" w Goto +4 SetFileAttributes "$INSTDIR\${UninstLog}" NORMAL FileOpen $UninstLog "$INSTDIR\${UninstLog}" a FileSeek $UninstLog 0 END SectionEnd Section "Install Main" ${SetOutPath} $INSTDIR ${File} "dir1\" "file1.ext" ${File} "dir1\" "file2.ext" ${File} "dir1\" "file3.ext" SectionEnd Section "Install Other" ${SetOutPath} "$INSTDIR\Other" ${File} "dir2\" "file4.ext" ${File} "dir2\" "file5.ext" ${File} "dir2\" "file6.ext" SectionEnd Section -closelogfile FileClose $UninstLog SetFileAttributes "$INSTDIR\${UninstLog}" READONLY|SYSTEM|HIDDEN SectionEnd Section Uninstall ; Can't uninstall if uninstall.log is missing!
