Hello, everyone.

I trying to run a macro that is based on SOLVER code. It was working perfectly however now appears this following message: "Solver: An unexpected error occurred, or available memory was exhausted"

It happen days ago and I solved it formatting my computer. But it happen again now and I think that it is not smart to format it again.

Hi and welcome to the forum.

We can't help unless you upload the workbook, and when you do clearly explain what you are trying to achieve

Hi Richard. Thanks!

Unfortunately I canīt share this workbook once there are confidential information on it. But my point here is that this macro was working very well until today morning when suddenly this message came up and it is not working anymore.

Main objective of this macro is to maximize some plants results using inputs values % of minerals and technologies.

This problem showed first time after I change my computer. And to solve it I need to format this new one. And now it appeared again.
