Excel can become unstable Excel can become unstable. Many times i have to remove the Frontline add-in from excel to improve stability. I use the add-in about 2 or 3 days a month so this is not something that is all the big a deal. If i leave it installed i have more issues with excel freezing up or stalling and generally i dump the add-in. The installation and annual update process was greatly improved.

Excellent support Frontline Systems has provided excellent support whenever I have had a problem. I recommend them and their products highly.

It needs some improvement to be a better product It needs some improvement to save .lp model. Some of the large models are not saved. It will be nice if it can track infeasible constraints the same as Gurobi. I also like to be able to import and export constraints from one model to another one. Such as selecting some constraints and import them in another model (in another Excel sheet).

Your product ir really excelent. Whatever, Your product ir really excelent, and the attitude on serving the customer is the best. Whatever, some points to improve: 1) I think that it would be ideal you define a Single Point of Contact, I'd had to receive and send mails to at least four persons last months. 2) When I add rows to my linear programming model, I have to go to constraints menu to update the ranges instead Solver do it automatically.
