Give Estimation of Installation Time

[Qiu]

There are quite a few instances reported in my ognization that user terminates the intallation process since it takes more than one hour and user tends to believe that the intallation process is somehow "failing". So they terminate the installation and try to install again.

A kind reminding message such as "This will approximatly take one hour, and you can enjoy your coffee break" something like that would definetely help.

Please kindly consider.
