  1. Hi OpenSolver Developers, thank you for making the powerful tool. I encountered installation problems with my new machine (macOS Catalina, version 10.15.6, Excel version 16.41). I downloaded the package and clicked on the “OpenSolver Solvers.pkg”, installed; and clicked on the OpenSolver.xlam, and enabled the macro, but nothing happened after that. I’d be happy to follow further instructions, or if the Google sheet option ever comes available, that’s also wonderful news.

  2. I have downloaded OpenSolver 2.9.0 and extracted it to a folder. However, when I try to open OPenSolver.xlam, I get a screen saying “opening OpenSolver” but nothing happens.
