I did an upgrade from Windows 7 to Windows 10 but all of sudden all macros using solver stopped working.
Running solver as a standalone do not work either as program complain about not finding solver.dll file. Checking the folder for Microsoft office I see that most of the files in the excel folder is gone. A reinstallation of Excel does not add the missing files.
Anybody has had this problem? The excel 2010 program has worked flawlessly for a number of years with Windows 7 as OS.
