Installing 1.5 on OS X 10.6.8

I am currently running 1.4.2 on OS X 10.6.8, when I run the 1.5 installer it gives an error on the hard drive "Serviio Installer can't be installed on this disk". I have repaired the file permissions and ran disk repair. 1.4 seems to load and run fine. I have made sure that the Serviio service is not running. I have also checked and my OS is running 64bit. Any help would be great.

your system doesn't meet the (new) minimal requirements : http://serviio.org/download

Feel like a fool, I read that page 10 times and saw the 64bit requirement but kept missing the 10.8
