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.

Great Solver with convinient interface Great solver with convenient interface

Great for optimizations In overall, we are satisfied with the product. We had few frictions due to: - license validation in big infrastructures (with proxies,...) - Instability of the plugin that gets desactivated in Excel - After calculations, the sheets get blinkering (switch betwen sheets, mouse cursor changing state,...) so we have to wait 1-3 seconds before the application stabilizes with some bigger excel files

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.
