Hi @bacherikov_iv , There exists no interface between AIMMS and SCIP, and therefore you cannot use SCIP in AIMMS. Adding a SCIP dll in the solver configuration will not work.

Connecting SCIP to AIMMS would require building an interface using the AIMMS Open Solver Interface, which is a lot of work. At AIMMS we currently have no plans for building a link to SCIP.

As a workaround you can just write your instances out in one of the many format that can be read by SCIP, such as .lp or .mps.
