Weird issue with installation

[Hpearl]

I'm running Mac 10.7.5 & currently flash 11.9.900.117 on firefox 25.0.1.  I was prompted to update so I clicked yes, & was brought  to  the installation page.  After I click "Install now," I am taken back to the adobe.com home page.  I have tried this repeatedly, over several days/times, but this happens EVERY TIME.  I have no idea what to do at this point. 

I hope i've provided enough info here.  If not, please let me know.  I also have a screenshot of the the installation page from which I am taken to the adobe home page, but i wasn't allowed to enclose it here for some reason.  Please help.
