Within the last couple of days Google ran an automatic update of Flash, which is causing havoc in the all-things-flash world.
Since Google manages the upgrade of the flash you are kind of at their mercy on this one, until all applications finally learn to stay as far away from flash as possible! Can only hope!
You can however disable the automatic update feature for flash by setting the registry HKLM\SOFTWARE\Policies\Google\Update\AutoUpdateCheckPeriodMinutes to 0.
My fix was pretty straight forward and I only had to delete the latest release folder from the path “%LocalAppData%\Google\Chrome\User Data\PepperFlash” (windows) or “~/Library/Application Support/Google/Chrome/PepperFlash” (MAC).
In my case the older version was still available in the same folder so I only had to delete the latest and restart google but if do not have the older version you can download it here.
From other users responses it seems that the version 18.104.22.168 and older still works but newer version will crash on both your Google Chrome and Firefox browsers.
Update: VMware has release a KB here
