can't install imac -technologically useless

I have a 2009 iMac. I have more than enough space on my built-in hard drive but when I go to install the Serviio is tells me it "cannot be installed on this disk" Why? Can I install it onto my external hard drive and still use it to stream from my desktop to my tv? Thanks!

Hi,

Have you already tried a "Verify Disk" and "Verify Disk Permissions" and subsequent repair, before install of Serviio?

What is your OSX version. Also, is it a 64-bit Mac?

There are new minimal requirements: http://serviio.org/download
