Can I still download version 4.5.1 (not 5.0)?

Can I still download version 4.5.1 (not 5.0) not Pro? I want to to follow some test procedures and use a project someone else wrote and created. I would like to use the exact version of SoapUI that they used which was version 4.5.1. I haven't had any luck finding a working link for version 4.5.1.
