Sharepoint - Products Configuration Wizard: How to add local account with Complete Server type option
I think you are trying to install Stand alone deployment and using the config wizard to create the configuration database using the local account. In this case you have to create the powershell command to create config DB 1st then run the config wizard.
Run this command.
New-SPConfigurationDatabase
Hit Enter and it will ask couple of question i.e Database Name, Database Server, FarmCredential, PassPhrase. After providing these, wait for couple of min once it created then re-ran the config wizard.
