This file is usually a leftover from installing OS X.

Backup your computer.

Move that file to trash.

See if that works without any problem.

Flash Player has to be uninstalled and a fresh copy has to be installed.

Uninstall Adobe Flash Player:

Look for these two files.

Right click those and select “Move To Trash”.

Make sure that there is no problem after that. Empty the trash.
