How do I install software from DVD on mini with no Optical Drive

I purchased Aperture on DVD at an Apple store in 2007 when the App store did not exist. The new Mac mini does not have an optical drive. I did not migrate applications from my previous Mac mini because it doesn't seem to let you choose which applications. (I had several legacy migrations involved and didn't want that junk on my new mini.) The App store, of course, does not know I've already paid for Aperture and wants to charge me to download it. I discovered you cannot install from another computer's DVD just by mounting that DVD on the target computer. It will tell you it can't install over the network. It also won't let you drag the contents of the DVD onto the target computer (which worked with Office 2011). It will tell you that method of installation is not supported. All Apple could suggest was to buy an optical drive which would have been almost anoher $100. Apple support doesn't seem to understand why Aperture is not in my iTunes purchase history (because iTunes didn't exist for Aperture then!)

I just had a wonderful discovery. I found this support article that details how you have to turn DVD sharing on under Sharing Preferences on the computer that does have the optical drive, then you can use the Remote Disc under Devices on the target computer to request use of that drive. Finally, the installer will run.

I'm putting this info here because I searched but was unable to find this subject in the Support Community. I'm sure someone has asked this question, but I couldn't form a query that would find it.

Article from Apple with instructions for Remote Disc

Now if someone could just tell me how to get the App store turned on for my copy of Aperture so I don't have this issue in the future when no Apple computer will have an optical drive!
