This may not be the best category for this, but it's a category.
Update the CommerceStoreScaleUnitSetup.exe installer to either allow the "." in usernames, or more broadly to follow Windows rules for allowed usernames.
The CommerceStoreScaleUnitSetup.exe installer (the Commerce Scale Unit sealed installer) does not allow installation under a username that contains the "." character. The "firstname.lastname" username convention is standard for my org (and many others), and having this constraint in the installer framework prohibits such users from installing locally for development and thus prevents from using the "F5 experience" for development, among other things.
This request is to relax the constraint on the "." character appearing in usernames since it is valid for windows usernames?
(Note: the ideas site is not allowing me to post the patterns as it detects them as malicious input, but I've listed them out in the links below)
