Hi Guys,
have a small problem with the Solver Add In. I am running a German Windows XP system and have an English Office 2003 Version.
My problem is that I cannot run the Solver twice. I know this sounds weird, but whenever I establish a Spreadsheet for the first time and run the Solver it works (with constrains etc.) . If I then try for example to run the Solver for a minimum instead a maximum (or the other way round), I get the "error in model" message which is DEFINITELY NOT the case, because if I copy my model into a new spreadsheet and run the solver with the same constrains it works.
I reinstalled Excel and the problem is still there.
I just do not know what to do!! This program is driving me mad and I have a presentation on portfolio optimization coming up!!!
I would be happy for any help,
Cheers,
Schaeft
