How do I get the Adobe Download Camera Raw 6.2 to work on my iMac??

[Myrnaf16]

I just Downloaded the 6.2 Camera Raw because I could not get Raw files from my Lightroom 5.3 to open in Photoshop CS 5.  Dialog box said could not recognize the source of the Download.  

Could not install.

Thanks, Myrna
