NSIS Script is not moving directory.... Please Help!

Yeah the only roadblock in making MoinMoinDE Portable is the wiki folder in Data\settings folder is not being moved back to App\moinmoin when MoinMoinDE is closed after the 1st run it moves the wiki folder to the Data\settings folder but 2nd run and so forth the launcher is not moving the wiki folder from Data\settings back to App\moinmoin

The wiki folder has 3 sub-directories

Heres the .nsi:

Please tell me what is preventing the wiki folder from being moved back to App\moinmoin
