    OK I'm now on Lion DP3 and trying to install DP4. I downloaded it from appstore but when i run the installer i get to the screen where you select the harddrive where to install...but the harddrive (the only on) on this computer is grayed and it says the computer cannot be booted from this hard drive or something like that.

    Is this a bug that you can't upgrade from DP3 -> DP4?

    Same problem

    I got the same problem just with my iMac Late 2009 with and SSD. i have replaced the DVD drive with an SSD and i can't upgrade to DP4 from DP3. i can only install it on the normal hard drive not SSD, so maybe it doesn't work on SSD?
