It says: <BR /><BR />"The file is an outdated Add-On that cannot be used with this Archicad.exe" <BR /><BR />What can I do to make the add on run in archicad13, 64 bit window 7? <BR /><BR /><BR /><BR />I am using visualstudio 2005 as my development platform <BR /><BR />Thanks <BR />Alfred</DIV> Thu, 03 Aug 2023 09:29:53 GMT https://community.graphisoft.com/t5/Archicad-C-API/problem-with-add-on-running-in-x64-bit-ArchiCAD/m-p/187431#M6064 Anonymous 2023-08-03T09:29:53Z https://community.graphisoft.com/t5/Archicad-C-API/problem-with-add-on-running-in-x64-bit-ArchiCAD/m-p/187432#M6065 sorted with setting active solution platform to x64 in vs2005.
