Hello everyone,
I'm a new user of this forum seeking help with a problem I've had for a while now.
I have an excel spreadsheet in which I use solver. It worked well for the last couple of years until recently. Now I find the error message: "A document with the name solver.xlam is already open" appears every time I try to launch solver from the Tools menu of my spreadsheet. I have tried to uninstall solver so that I can re-install it but when I try to move the solver add-in to the "trash", it refuses to go saying "Can't move solver to Trash because it is in use". This happens even when I have quit Excel and StatPlus.
I upgraded to Lion a few months ago. Could this problem be related to the upgrade? How do I solve my solver problem?
Dave
