Installdir from Registrypath ... but how to go to ..\ - 2 Questions

Hi there,

I am getting my installdir from the uninstallpath in the registry.

InstallDirRegKey HKLM Software\Microsoft\Windows\CurrentVersion\Uninstall\TobWen "UninstallString"

Returning is "C:\progs\bla bla\runme"

How can I go back to "C:\progs\bla bla" and set it as $INSTDIR ?


Another question is:
SetOutPath $PROGRAMFILES\TobWen
CreateDirectory "bla bla"
SetOutPath "bla bla"
File ....

Where is the error?
It copies the files anywhere ... but not into this directory.

Thanks
Tobias

To get the parent dir, use the GetParent function that is in
functions.htm. i.e.:

Function GetParent 

  Exch $0 ; old $0 is on top of stack

  Push $1

  Push $2

  StrCpy $1 -1

  loop:

    StrCpy $2 $0 1 $1

    StrCmp $2 "" exit

    StrCmp $2 "\" exit

    IntOp $1 $1 - 1

  Goto loop

  exit:

    StrCpy $0 $0 $1

    Pop $2

    Pop $1

    Exch $0 ; put $0 on top of stack, restore $0 to original value

FunctionEnd



...



and in your first section, something like:



Push $INSTDIR

Call GetParent

Pop $INSTDIR

As for the second question, what are you doing wrong, do this:

SetOutPath $PROGRAMFILES\TobWen

...

SetOutPath "$OUTDIR\bla bla"

File..

or, if you want to do it more quickly, use:

SetOutPath "$PROGRAMFILES\TobWen\bla blah"

note that setOutPath creates the directory as well.
