Data Gateway strange message from an attempt to re-install

[KathyPullin]

I attempted to re-install the Data Gateway, which appeared to go fine, until it finished, that's when I received the message below.  Not sure how well the text can be seen, it states:  "You have successfully Something unexpected happened, the on-premises data gateway."  Not sure how to take that, as it appears I'm successful and yet, something unexpected happened.  Any one have any ideas?

@KathyPullin Never seen this before but I would suggest you completely uninstall data gateway, remove all registry keys, files, folders and then try to install new one. Maybe @GuyInACube can help.

Thank you Ankit, I will attempt to clean it up and re-install.  If it works I will mark your reply as the solution.
