I see a bug opened at Adobe about this.
https://tracker.adobe.com/#/view/FP-4199035
Need an account (free to open one) to view the bug but in short, the Flash Actionscript navigateToURL() call looks like it’s being blocked in Flash 32.0.0.255.
The workaround suggested in the bug is to add “EnableInsecureActiveXNavigateToURL=1” flag in the MMS.CFG(C:\Windows\SysWOW64\Macromed\Flash) file.
The MMS.CFG file didn’t exist on my system so I created it and adding the flag got the links working again.
