Hi everyone,

I'm currently working on an academic project that requires accessing and adapting a legacy model originally developed in AIMMS 3. When I try to open the project using the current version (AIMMS 25.4.2.1), I get a message saying I need to first open it in AIMMS 4.90 or earlier to convert it to the new format.

Would anyone happen to have access to the AIMMS 4.90 installer (or the latest version prior to it that supports AIMMS 3 project conversion)?

Also, does anyone know if a license tied to version 25.4.2.1 is compatible with AIMMS 4.90? Or would I need a separate license for that? If so, how can I ask for it?

This is for academic, non-commercial research. Any help would be much appreciated!

Thanks in advance,
Hugo
