RC2 install error

I just tried to install the RC2 over RC1 and received the follwoing error: “Rhinoceros” is damaged and can’t be opened . you should move it to the trash. It worked fine after a clean install, but it was curious nonetheless.


I just had the same problem, but seconds after closing the box, tried again and it opened ok. Not sure if I can replicate it here…

Anyone else having the same problem?
