I am sorry you have had problems. My instructions were not clear enough.
It looks as if you did not copy the downloaded the file into the C:\WUTemp folder. Try to find where you downloaded the file - probably the Downloads folder. Right click on the file then select Copy or Cut. Create WUTemp as a new folder on the C:\drive and then double click on it. The folder should be empty and you can then right click and select Paste. This should then add the file to the folder.
You can than repeat the three commands and see if they work this time.
