I accidentally downloaded Adobe flash twice and not sure if it is duplicated in my system or if it is only there once? Is there something within the program that prevents from it duplicating? It looked like it went through the same entire download to 100% on each account. When I look in my applications (I have a MAC computer), i only see one copy of it, but I don't know why it allowed me to download it two full times if theres only one copy? Help with this would be appreciated!!!
