Safari Plug-ins

If you know you have installed the latest version of the FlashPlayer, but cannot play a Flash file in Safari it is because Safari cannot find the plug-in files it needs.

You will need to find the following files:
NPSWF32.dll
flashplayer.xpt
NPSWF32_FlashUtil.exe

You should be able to find the files either in Firefox's plugins folder or alternatively in \Windows\System32\Macromed\Flash

Once you have located the files listed above, copy them and paste them into Safari's plug-ins folder: \Program Files\Safari\plugins

You should now be able to use Safari to view Flash files.
