It doesnt replace the standard archicad 22 windows with the windows in the 21 libary.<BR /> <BR /> Ive used the 'Window 22' thinking it would replace with 'window 21' in the previous version.<BR /> <BR /> Is backward migration possible with the new 22 libary? it has worked fine before (saving a 21 file as a 20 file..it replaces the windows automatically)</T></DIV> Mon, 21 Jan 2019 12:57:17 GMT https://community.graphisoft.com/t5/Project-data-BIM/Backwards-libary-migration-from-Archicad-22-to-21/m-p/277231#M1233 Anonymous 2019-01-21T12:57:17Z https://community.graphisoft.com/t5/Project-data-BIM/Backwards-libary-migration-from-Archicad-22-to-21/m-p/277232#M1234 Hello,<BR /> You'll find the solution here:<BR /> <A href="https://archicad-talk.graphisoft.com/viewtopic.php?p=288498#p288498" target="_blank"><LINK_TEXT text="viewtopic.php?p=288498#p288498">https://archicad-talk.graphisoft.com/viewtopic.php?p=288498#p288498</LINK_TEXT></A><BR /> Regards, Mon, 21 Jan 2019 13:53:40 GMT https://community.graphisoft.com/t5/Project-data-BIM/Backwards-libary-migration-from-Archicad-22-to-21/m-p/277232#M1234 felcunha 2019-01-21T13:53:40Z
