Adobe flash installer launches another application on Mac OS X 10.11.4 El Capitan

Question

I am trying to install Flash player on Mac OS X 10.11.4…. when I double click the installer file 'AdobeFlashPlayer_21_a_install.dmg.mdlp', it launches another application ( Matlab_R2014a) instead of starting the installation process. I have tried following the clean installation process by removing the flash installer plugin and installation manager folders, but didn't work. I have also tried moving the AdobeFlashPlayer_21_a_install.dmg.mdlp file to another location (desktop) instead of the downloads folder and launching from there but didn't work.

Any help would be appreciated.

Hi,The installer downloaded is most likely fine. Delete .mdlp from the file name and the installer should launch correctly.We've seen this happen in the past, and it happens to other products not just Flash Player installer. For some reason, on some systems that have Matlap installed, .mdlp appends itself to the end of the file name resulting in the behaviour you are experiencing. Simply removing .mdlp, leaving only the .dmg file extension, enables the installer to launch correctly.--Maria
