Search for instances of SOLVER.XLAM (including hidden files and folders). Maybe there is an instance of SOLVER.XLAM in a startup folder as well as one being opened as a result of having Solver add-in installed. I will be glad if you solve this problem. Cannot run the macro 'SOLVER.XLAM!GetSolverLabel'., Even if I uninstalled Office products on my PC, the error was not solved.
