The AGREE plugin is only packaged with the SMTInterpol SMT solver. If you want to use other solvers (Z3, Yices (version 1), Yices 2, CVC4, or MathSAT) you will need to obtain them separately and set your PATH environment variable to point at their location. In order to perform Realizability Analysis you must have Z3 installed.
If you have trouble installing the updates you might need to run OSATE as administrator.
