It's still in there. Here's how to get it:
1. Unzip the 2.0 installer as you normally would to get to the setup.exe file.
2. Close all running applications, including most of the crap that runs in most people's system tray. (This is to make step 3 cleaner and easier)
3. Navigate to the temp directory in Windows Explorer (different on various OS's... if you wanna know exactly where it is, type SET at a command prompt and look for the TEMP environment variable).
4. Delete everything in the temp directory that it'll let you delete.
5. Now run SETUP.EXE but don't close it or answer any questions. Just leave it up on the screen.
6. A new folder should now exist under temp, and since you just cleaned it out, it'll be easy to see which one it is.
7. The enlightenment, er, MSI file you seek is in that folder, Grasshopper.
