I started my project on Dialux 13, however deep into the project, there were many errors with importing different ifc files, with regards to alignment and coordination. It was a big pain to work with, simple things such as placing or moving a fixture along an axis does not follow the curser and create awkward shapes. Furthermore, the 3D view was a hassle to move around.

As such, I downgraded to version 12.1 and the ifc imports worked perfectly!

However, all the files I have created on Dialux 13 do not open anymore, since I am only allowed one version on my PC.

What is the solution to this? I need access to the files I created on version 13 to open in version 12.1
