We can download the setup of Adobe Flash player from the website
http://get.adobe.com/flashplayer/ (Please select the right OS)
While installing the applcation when you get the error message to close the IE , go the task manager and then in process tab look for iexplore.exe.
When you locate the service, right click on it and click on end process and then resume the installation for Adobe Flash Player.
Hope It Helps.
