I have the exact same problem trying to install flash player 16 today. I'm running OS X 10.8.5 and Safari 6.2.2. I've uninstalled MATLAB, but it doesn't help.
The downloaded file is somehow not a .dmg but a .mdlp, whatever that is, and is a lot of nonsense in a txt file just like for lopesdan above.
It named itself: AdobeFlashPlayerInstaller_16_ltrosxd_aaa_aih.dmg-2.mdlp
Please help us!
hagge, based on your note, I tried simply removing everything appended after .dmg and it seemed to run OK. So, there is at least a workaround. I guess the question is: what is appending the .mdlp extension?
That did the trick!
I've seen this same post about a dozen times over the last couple months. If anyone figures it out, I'd love to know. Is there maybe a matlab browser extension or something that gets installed?
