Also asked, how do you reset Solver in Excel?

1. In the Solver Parameters dialog box, click Reset All.
2. In the confirmation dialog, click OK. The By Changing Variable Cells box and the Constraints list box are cleared, the Set Objective box is set to the active cell, and all Solver options are reset to their default settings.

Why can't Solver find a feasible solution?

"Solver could not find a feasible solution:" means there is not even one set of values which staisfy all the constraints--infeasible problem. "The Objective Cell values do not converge" means there is no limit to the objective function value.
