The information in this article applies to:
When I 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 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?"
Select Yes to associate plan, layout, and library files with this version of the program, or choose No if you want plan, layout, and library files to be associated with the program version you last chose.
If you're not receiving this prompt and files aren't opening correctly in the program version you'd like to use, please follow the steps listed in this article.
Plan, layout, and library files will now be associated with this program version.
