Outlook (again!) GWSO issues with existing profiles.. after upgrading from Office 2016 (32 bit) to O365 64

The GWSO tool is great. But if you have an existing profile that uses this, then when you come to reinstall it, you get the following weird cryptic message: A profile for Google Workspace sync (named 'temp') already exists - you're all set! If you need to create a new profile, please use the 'Setup a Google Workspace Sync user' option from the Start menu. This made no sense (as I had deleted the current gwso profiles I saw in Control Panel Mail profiles..) until I looked in the Windows Start menu and lo and behold there was a new entry to do just that. This quickly ran through the credential prompts, created the new gwso profile as it said it would!
