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 try to open a file that was given to me by another party, this Warning message appears:

"This plan cannot be opened.  It was written by a newer version of the program than you are currently running.  You may want to check for and install any available program updates."

Why can't I open this file?


A given version of Chief Architect can open files created in that version, and also in previous versions.  It cannot, however, open a file created in a more recent version of the software.

For example, Chief Architect X5 can open files created in version X5 or version X4 - but it cannot open files created in version X6 or X7.

If you are encountering this Warning message when you try to open a particular file, then the file was created in a version of the software that is newer than the version you have.


You may be able to resolve the issue by downloading and installing the latest program update for your software:


If running the latest update does not help, you may want to consider upgrading your software license to the latest program version:
