Sometimes no matter how much you try you just can’t get chrome to get rid of those annoying warning messages about your flash player version. I had a strange problem which I was able to debug by going to this url: chrome://flash/.

You’ll notice something like this in the begining:

Google Chrome 45.0.2454.85 (m)
OS Windows 7 or Server 2008 R2 SP1 64 bit
Flash plugin 18.0.0.232 C:\Windows\SysWOW64\Macromed\Flash\pepflashplayer32_18_0_0_232.dll
Flash plugin 18.0.0.232 C:\Program Files (x86)\Google\Chrome\Application\45.0.2454.85\PepperFlash\pepflashplayer.dll (not used)

If you see two Flash plugin lines then you’re in the same boat as me. I happen to have installed two versions of flash (and forgot about it). I have the regular version installed as well as the debug version. The regular version was up to date but the debug version was not. So that is why chrome was complaining all-along.

Solution

1. Update the debug version of Flash from here: http://www.adobe.com/support/flashplayer/debug_downloads.html
2. Disable the debug version of flash in chrome. Go to: chrome://plugins/ Click on details on the top right. Find the debug flash player and disable it.
3. Uninstall the debug version of Flash. Follow instructions here: https://helpx.adobe.com/flex/kb/uninstalling-flash-player-debugger.html
