+1 for this.

 

Also - fix the huge delay (3-6 minutes) caused in the "configuring Windows features" step of the installer.  This happens both during the install and uninstall process.  I'd suggest having an option in the uninstall process that leaves the configured Windows features alone rather than trying to remove them each time, so that a subsequent install immediately thereafter didn't need to re-configure the Windows features every time.  Since the uninstall is part of the official upgrade process, there should be two versions of the uninstall: 1) Uninstall forever (not going to reinstall), or 2) Uninstall for upgrade (leave most things intact).

 

Beginning with the first release of December 2018, the installer has been significantly reworked. As long as you don't perform an uninstall before installing an upgrade, the installation location should be preserved. You can also now indicate that you want to use an IIS site that has already been configured, which should reduce your upgrade time.

The location was not preserved when upgrading to 7008 from a previous 'v17' build. It was necessary to correct the location during install.
