I have previously been using AC15. I had intended to finish my old projects in AC15 on my old machine. This morning I came in and the old machine is looking pretty dead. I would still prefer to use AC15 to finish the existing projects as I have not completed the existing projects. When I tried to install AC15 on the new machine it did not work. I assume that is because windows has stopped supporting quicktime. <BR />Can anyone offer me some advice. I have a lot of projects which are time sensitive.<BR />Cheers Jo</DIV> Mon, 25 Mar 2024 08:52:58 GMT Anonymous 2024-03-25T08:52:58Z https://community.graphisoft.com/t5/Installation-update/upgrading-15-to-20/m-p/226938#M23862 <DIV class="actalk-migrated-content">Hi,<BR /><BR />I have a new you-beaut computer in preparation of the upgrade to ac20.

I didn't realise that files could be imported in the Legacy format.
