Where to download the Parallels 6 installer

I'm needing to migrate Parallels 6 from one hard drive to another (on the same computer), as a result of re-installing Lion.

Apple's migration tool refuses to migrate the Parallels kernel extensions (complains that they're not installed correctly, although they work just fine), so I need to reinstall them.

My (downloaded) Parallels 6 installer has gone missing, so I need to download another copy.

Every method I've used to find the Parallels 6 installer leads me to the Parallels 7 download page.

So, my question is, where can I download the Parallels 6 installer?

 

On the Parallels 7 download page (Bottom right corner).
