ReadRegStr
  I have a littel problem.I want read the install dir from the reg.But i get a "" in the installdir.Waht is wrong.

Function GetMyInstPath
ReadRegStr $0 HKCU "Software\Mysoft" "MyDir"
FunctionEnd


; The default installation directory
InstallDir $0

; The text to prompt the user to enter a directory
DirText "This will install the very simple example1 on your computer. Choose a directory"

; The stuff to install
Section "ThisNameIsIgnoredSoWhyBother?"
; Set output path to the installation directory.
SetOutPath $INSTDIR
; Put file there
File "C:\windows\notepad.exe"
SectionEnd ; end the section

; eof

A function doesn't get called by itself, you must call it from a section or a callback function. Anyway, you don't need to do it yourself, just use InstallDirRegKey.

If you have two possible install directories, manage them in .onInit.

onInit

  ReadRegStr $INSTDIR HKLM "Software\\mysoft1" "myDir"

  IfErrors 0 done

   ; if we couldn't read the reg key read the second one

    ReadRegStr $INSTDIR HKLM "Software\\mysoft2" "myDir"

    IfErrors 0 done

      ; if we can't read this one either just use default

     StrCpy $INSTDIR "$PROGRAMFILES\MyProg"

 done:

>FunctionEnd
