The Myst Series - Revelation

I have played most of the Myst games except for the last one.
Revelation. I purchased the game over a year ago but have not played it yet. The game asks me to uninstall my virtual drive before it will allow me to load the game. I would like to play the game. I don't feel that I should have to uninstall a program on my computer to use another. I paid for the game and now cannot play it unless I uninstall something else. I really think this is unreasonable. The virtual drive is installed so that I don't have to use a disc to run programs, therefore speeding up load times and saving wear and tear on my disc.
On another note, Myst, the first game was one of the absolute best games that I have ever played. All other Myst games that followed just in my opinion could not compare.
The Exile came close to being like the original game play.
I am hoping Revelation gets back to the game play of the original game. I loved hunting for pages and being teleported into another space and time.
What were your favorite Myst games? Do you think any compared to the original? Has anyone else encountered this problem with Revelation?
