I tried putting a Gogii game disc (which contains 4 casual games) in the CD drive of a Windows 7 computer. I had a problem with things wanting to autoplay when they shouldn't -- both when I inserted the CD and when I tried to open the drive by clicking on it. If you're going to use Run As, you definitely do not want to let Autoplay start up because it won't run the Setup in Administrator mode... and if the games aren't run in Administrator mode, they apparently won't install. So cancel out of everything that pops up automatically. And when I double-click the drive, it wants to autorun instead of simply opening the drive in Explorer the way XP used to do.
So these instructions are going to be a little different than what I originally told you in that you don't double-click the CD drive.

You can get the drive to show up by using the Start button in the lower left of your computer and clicking Computer. And I get something that looks like this:

If any windows open automatically, cancel out of them.
Now right-click the drive and you should see a context menu from which you can choose Open. Here's a picture:

There's also the possibility that you have an antivirus wanting to scan the disc before allowing anything on it to run. If that's the problem, you can probably just wait and let it finish scanning before trying to install.
