How to get the parent directory
For example the script:
!include "MUI.nsh"
SetCompressor /SOLID lzma
InstallDir "$PROGRAMFILES\MYPROGRM"
......
Section Client
${GetParent} $INSTDIR $R0
......
SetOutDir "$R0\TEST"
......
When compiling,it said:
Invalid command: ${GetParent}
How to use the function "${GetParent}"?Help me!
The help give the follow code:
Section
${GetParent} "C:\Program Files\Winamp\uninstwa.exe" $R0
;$R0="C:\Program Files\Winamp"
SectionEnd
But I test it,it can't be compiled!
