I have a educational version of Archicad 12. I have downloaded the add-on and i think it is located in the right place, the problem is when i click on "Open Architerra 3 toolbox" under Extras&gt;&gt; Architerra 3 I get this error: <BR /> Warning: <BR /> Protection key is not responding <BR /> or <BR /> Protection key not found or not valid <BR /> Error code: 105 <BR /> <BR /> I am wondering if i need to actually have a device from the company. Or if i am just missing something. please help. I am trying to create a topographic site plan for a 150 acre project and from what i can tell if i can get this to work i'll save a bunch of time over using the mesh tool. <BR /> Thanks in advance. <IMG src="https://community.graphisoft.com/legacyfs/online/emojis/icon_smile.gif" style="display : inline;" /></R></DIV> Tue, 20 Oct 2009 06:39:16 GMT https://community.graphisoft.com/t5/Collaboration-with-other/ArchiTerra-error-Protection-key-not-responding/m-p/120249#M12271 Anonymous 2009-10-20T06:39:16Z https://community.graphisoft.com/t5/Collaboration-with-other/ArchiTerra-error-Protection-key-not-responding/m-p/120250#M12272 You must download the add-on from the Graphisoft educational download site here:<BR /> <A href="https://eduregistration.graphisoft.com/" target="_blank">https://eduregistration.graphisoft.com/</A><BR /> <BR /> I'm just guessing that if you download from the Cigraph web site, that those versions of the add-on will only work with a purchased USB protection key.<BR /> <BR /> Karl Tue, 20 Oct 2009 16:31:57 GMT https://community.graphisoft.com/t5/Collaboration-with-other/ArchiTerra-error-Protection-key-not-responding/m-p/120250#M12272 Karl Ottenstein 2009-10-20T16:31:57Z
