How to Create a Local Administrator Logon in Windows

[Product_Support]

Issue

Continuum 1.9x and above may fail to install correctly on domain-joined machines. A common error during installation is:

"You must have local NT administrative privileges to run this application."

Product Line

Andover Continuum, EcoStruxure Building Operation, Satchwell BAS & Sigma, Satchwell MicroNet, TAC IA Series, TAC INET, TAC Vista

Environment

• Windows 7, 8, 10, 11, Server 2016 and later
• SQL 2005, 2008, 2012 and later

Cause

Microsoft SQL installations require elevated local administrator privileges. Domain accounts often lack these rights due to group policies or security restrictions. A local administrator account is required to complete the installation successfully.
