DARN IT.
OS X Yosemite
OS X Yosemite JUST says app store download and doubleclick take me to app store.

and this one more promising:

Install OS X El Capitan says application
But when double click it is says, "the copy is too old to be opened in this version.."

Wonder if it'll be ok in Parallels..

Wish I had more Installs, wonder why only El Capitan is in my apps folder and not other 10 from over years?
