Removing parent directories

[tderouin]

Our current installation installs our product to something like:

C:\Program Files\CompanyName\ProductName

During the uninstall,

PHP Code:

  RMDir /R "$INSTDIR" 


will only remove the ProductName folder, leaving an empty CompanyName folder.

Is there a smart way to remove the folder CompanyName? As far as I can tell there is no way to capture which directories are being created by the installer. Hardcoding

PHP Code:

  RMDir /R "$INSTDIR"
  RMDir /R "C:\\Program Files\\CompanyName" 


isn't a viable solution, because the problem still exists for non-default installations that have subfolders (and this problem also exists for removing shortcuts).

Also, doing something like

PHP Code:

StrCpy $R0 $INSTDIR
loop:
      RMDir "$R0"
      IfErrors goto done
      StrCpy "$R0" "$R0\\.."
      goto loop
done: 


isn't a (completely) viable solution because you might end up deleting an empty directory the installer didn't create, that the user doesn't want deleted.

Suggestions?
