I need to use the solver add-in for my studies. However, Every time I try to use it I get an error: "Cannot run the macro 'SOLVER.XLAM!GetSolverLabel'. The macro may not be avaliable in this workbook or all macros may be disabled."
Even if I uninstalled Office products on my PC, the error was not solved.
Thank you for trying to solve it, but it the error actually appear after add-in is enabled (through options like you say) and after you try to use it (press on solvers button) it shows an error "Cannot run the macro 'SOLVER.XLAM!GetSolverLabel'. The macro may not be available in this workbook or all macros may be disabled."
I've recently encountered a similar issue with Solver. Uninstalling and installing office 365 did not work. The issue I think was caused by 32bit vs 64bit incompatibility yet when I checked office, windows, and my laptop they were all 64bit. Then once, when I was uninstalling MS office I noticed that there was another office app that came with my laptop called "WPS Office" which is freeware shipped with Asus. Since I was not using it, I decided to uninstall it. And voila that made solver work again.
