Solver Add-In very slow after updating to Windows 11

[torszulak]

Has anyone experienced a significant slow-down using the solver add-in (Excel, Office 365) after upgrading to Windows 11?  Before, my model would run in less than a second.  Now it takes about 15-30 seconds to run a simple iteration.  Has anybody else experienced anything similar to this?  Any ideas for solutions?

Thanks!

Solver completely disappeared for my when I upgraded to Win 11. I have been trying to get it back for the last 30 min. If anyone knows how to get solver back, please let me know. @torszulak
