I want to make sure that if I get a PPU key, that I can still access my older AC14 EDU files for reference, but also to complete my personal house remodel plans i did with the EDU version to keep up my CAD chops while I was back in school.

I just installed AC15 Trial. None of my old 14 files will open. I get this error message: Trial edition cannot read this document version. (14.0). <BR /><BR />any ideas on how I can open these files in 15? Do I need to migrate them, or something else?<BR /><BR />Paul</DIV> Tue, 02 Apr 2024 07:31:32 GMT https://community.graphisoft.com/t5/Installation-update/Trial-edition-cannot-read-this-document-version-14-0/m-p/123367#M14534 Anonymous 2024-04-02T07:31:32Z https://community.graphisoft.com/t5/Installation-update/Trial-edition-cannot-read-this-document-version-14-0/m-p/123368#M14535 Does anyone know if my conflict is because I'm trying to open a AC14 EDU file with a AC15 Trial version?
