Usage of old versions

[eneskaraca]

I have an Archicad 26 education license and am using that version but I need Archicad 18. Can I use Archicad 18 with my student license? And can I have both versions installed on the same

Operating system used: Windows 26

It could work if you have a valid EDU license but curious as to why as a student do you want to use a 10 year old version.

Version 26 can open a version 18 file, so you shouldn't need to install 18 at all.

Our instructor use old version of the archicad so I need to covert to ifc file to send them. But it broke the walls opening etc. How can translate with the same element types from archicad 26 to archicad 18.

[Barry Kelly]

If 18 can use IFC files, it is probably locked into a very old version that is not compatible with 26.

To save back from 26, you must 'Save As' a version 25 file. (change file type in save as dialogue).

Then open the file in 25 and save as 24.

Open in 24 and save as 23 - all the way back to 18.

So you will need to have all versions from 19 to 26 installed on your machine.

I would be telling your instructor it is time to upgrade.

He is not a very good instructor if he is still using version 18 which is nearly 10 years old.
