Thank you for bringing this to our attention.
After seeing this behavior on my PC, I reached out to @Lior_Manor who manages the Deployment R&D group. They are responsible for our installer and will look into this to see how it can be improved. The goal is to remove the request for a reboot and to make sure the directory is deleted so that a new installation can happen.
Separately, as I mentioned, we are also working on an automatically updatable SmartConsole which will remove the need to deal with downloading and installing a new version altogether.
Last, I definitely want to encourage people to raise such issues on this forum. If something requires improvement, we want to know about it.
