Hi,

You can use a method similar to that in the following thread:

Though I'd use GetTempFileName so it won't overwrite any files.

!define MUI_PAGE_CUSTOMFUNCTION_LEAVE OnDirLeave
!insertmacro MUI_PAGE_DIRECTORY
Function OnDirLeave
  ClearErrors
  SetOutPath "$INSTDIR" ; what about IfError creating $INSTDIR?
  GetTempFileName $1 "$INSTDIR" ; creates tmp file (or fails)
  FileOpen $0 "$1" "w" ; error to open?
  FileWriteByte $0 "0"
  IfErrors notPossible possible
  
notPossible:
  RMDir "$INSTDIR" ; removes folder if empty
  MessageBox MB_OK "Not able to write into this directory!"
  Abort
possible:
  FileClose $0
  Delete "$1"
FunctionEnd
