I am attempting to install Adobe Flash Player.
I have downloaded the file from - http://get.adobe.com/flashplayer/download/?installer=Flash_Player_11_f or_Other_Browsers&os=Vista&browser_type=Gecko&browser_dist=Firefox&d=M cAfee_Security_Scan_Plus
However, when I click Run, the box closes and I cannot see anything being done. If I try to Run the program again, it says 'Only a single instance of this application can run'.
If I go to Processes on Task Manager, I can see it there but I cannot see it actually installing.
End the process, as instructed by Sunil, then download and run the offline installer from http://helpx.adobe.com/content/help/en/flash-player/kb/installation-pr oblems-flash-player-windows.html#main-pars_header
