I have the Developer SDK for 25 installed. I am now trying to install Archicad 25 trial but am unable to get to anything other than 26. Will 26 work for testing an extension written with the 25 sdk?</P> Fri, 09 Sep 2022 15:07:18 GMT Dismiss 2022-09-09T15:07:18Z https://community.graphisoft.com/t5/Archicad-C-API/How-to-get-Archicad-25-or-older-versions-and-which-do-i-need/m-p/355553#M4685 <P>I'm trying to get into tool / extension development for a project that is currently using Archicad 25.
