Nice and simple conversion!
But got this on my mind - could you add San Andreas to this? (if it fits DVD5 of course)
Second - I had to look for the "Start installation" button for a while, the icon with tools indicated to me something like setting of a installation, not the start and it's not particularly clear that it's clickable...
And third - could you switch the next and back buttons in installation? After clicking custom install it's a little bit inpractical to move the mouse to left to get it forward
Anyway, good work and nice music in installation
