although NEMO was working fine for some time, suddenly I started getting the message "Julia plugin for CbC not found" and the same for SQLite, GLPK, JuMP when I start LEAP.
I have uninstalled and re-installed LEAP and NEMO but the problem remains.
I encountered the same issue, which may have been caused by other programs occupying the solver. When I closed those programs, the problem was resolved.
