I've been attempting to install Flashplayer, but keep getting the message that only a single instance of the application can run. Have tried various things but not getting anywhere.

Can anyone assist? Thanks.

Does this error appear after you complete the download and start up the installer file? If so, you may need to restart Windows. Sometimes the Windows Installer accumulates a backlog of changes and stops working correctly until you restart your system and let it clear its queue.
