How do you make Inno Setup not look frozen while performing a long Exec?

Question

The long Exec is installing .NET 3.5, and out script is based off this one: http://www.blackhillsoftware.com/blog/2006/06/26/using-innosetup-with-the-dotnet-fra

Answer 1

We've needed to install .NET with a couple products, and have taken two approaches:

• When installing .NET with Innosetup, we let the user know that the installation will take a long time, and to expect a certain message when it is complete
• We start the .NET set up without any flags to force the client through it. This way if they're more technically inclined they know why the install is taking so long

We've honestly had better luck with the 2nd option, particularly now that more system admins seem to lock down desktops to a certain degree.
