After installing the software I see it is set to use the IEC standard, which I don't use. How to change it to the ANSI-IEEE standard?
During installation, the wizard presents a dialog for the person installing the software to choose the Standard. The default selection is IEC (metric), the other option is ANSI-IEEE (inch).
If the software is installed with the undesired standard chosen, this can be changed after installation without re-installing the software.
This article assumes the installation and configuration of the software were successful except that the "wrong" standard is being used.

Enter or paste the Server name and Database values noted in step 2.

It is not necessary to create a new project database for each setup configuration or when changing to a different electrical standard.
