Dear Marwa, The download page has a link to this “old releases” page: <http://www.rbvi.ucsf.edu/chimera/olddownload.html> You have to scroll down to the “32-bit releases” section lower in the page.

Dear UCSF Chimera team,

I highly need to use the software Chimera, but unfortunately, my operating system is 32-bit which is no longer supported. I would like to ask if any old release of chimera that I could download on my 32-bit operating system. Could you please help?

Regards, Marwa
