Hi Richard,
See below...
I'll pass this on to Mark.
We'll improve the interaction as we progress through Alpha.2. One thing with the install though was that I only found out to check the above when I read through the dialog after the WebApp Check dialog. Maybe the link that appears on the WebApp Check when it fails could open this dialog up.
Many changes in IIS require a reboot so we err on the side of caution and require the installation to be restarted as well. Don't think we're going to change this.3. I left the install dialog open, fixed the IIS setup by checking the IIS Metabase checkbox, went back to the install dialog and reran the WebApp Check which then came up green for IIS, clicked next but the IIS not installed configuration dialog still appeared. I had to restart the install for it to not show. Perhaps a property isn't being reset after the initial fail.
There is a different mode when started as part of the installation and when started stand-alone. The stand-alone checks things about the currently running WebApp server (which wouldn't be there at the start of the installation).2. I can see a DataFlexWebAppCheck in Users\AppData\Local\Temp which when I run shows a slightly different screen with a breakup of IIS components showing. Just curious as to why it's different to the one from the install dialog.
