Associating Plan, Layout, and Library Files with the Latest Version of Chief Architect

Reference Number: KB-01131
Last Modified: October 11, 2018

The information in this article applies to:

Chief Architect Premier or Chief Architect Interiors

Home Designer Professional or Home Designer Architectural or Home Designer Suite or Home Designer Interiors or Home Designer Essentials


When I go to double click on a .plan, .layout, .calib or .calibz file, the version of the Chief Architect software program that launches is not the version that I want to use.

How can I change this file association within Windows so that the version of Chief Architect I want will open when I double click on these file types?


If you have just installed a new version of Chief Architect or Home Designer, you may receive this message upon launching the software for the first time:

"Do you want to associate plan. layout, and library files with this program?"

Yes to associate plan, layout, and library files with this version of the program. 

If you would like to re-associate these file types to use a different version of the software, please see the appropriate online Help Article for your operating system.
