Can't disable Next/Install on directory page
  I need to disable Next/Install button on directory page to make additional checks for specific files required for installation. User should not be able to see enabled Install button until correct directory is chosen.

I disable Next button in pre-, show- and leave- functions of directory page, but it becomes visible again as soon as function exits. Are there any workarounds? Can it be fixed in next release?

OutFile "test.971.exe"


>Page directory "" makeDisabled checkFiles

Page instfiles


>Function makeDisabled

  GetDlgItem$0 $HWNDPARENT 1 # next/install button

 EnableWindow $0 1

  MessageBox MB_OK "$0"

>FunctionEnd



>Function checkFiles

  GetDlgItem$0 $HWNDPARENT 1 # next/install button

 EnableWindow $0 0

  MessageBox MB_OK "$0"

  Abort

FunctionEnd



Section

DetailPrint $INSTDIR

SectionEnd

That's what the .onVerifyInstDir callback function is for. Just call Abort from it and the Next button will be disabled for you.
