Just in case 8.0 doesn't work???

[rookwood]

In the event 8.0 causes problems or doesn't install properly, will it leave 7.0 intact? You would think so since it is called Revit Building 8.

Also, the instructions say that, for AutoCAD Revit Series, you must run in trial mode until you receive your CD with the serial number? If this is correct, I would assume there are no limitations while running in trial mode.

The installer will give you the choice of removing or keeping older versions that it has searched for on your machine.

...And there are no restrictions on running it in trial mode... just you only get 30 days before it self-destructs! ;)
