Question about setting the output path

[wrybread]

I'm trying to let users browse to whatever folder they'd like to install a package, but my NSIS script keeps adding the directory name of InstallDir to their selection. For example, if my default InstallDir is set like this:

InstallDir "c:\test1234"

But the user browses to c:\pics, it will then try to install to c:\pics\test1234.

Is there a way to take the path they browse to, without appending the InstallDir (in other words, without the "test1234" subfolder in the above example)?

Here's my stripped down sample script:

code:
;Include Modern UI

!include "MUI.nsh"



Name "Teste123"

OutFile "Test_Installer.exe"



;Default installation folder

InstallDir "c:\test1234"



;Pages

!insertmacro MUI_PAGE_DIRECTORY



;Installer Sections

Section "ASDF" SecDummy

  SetOutPath "$INSTDIR"

SectionEnd
