Hi All

I hope you are all fine.

I have this 70 MB Excel model and I want to open the file twice and be able to run the two files at once.

I once tried open two instances, and it worked I managed to click on 'RUN' nearly at the same time.

Now the two instances trick is not working at all, not sure why.

I appreciate your help if there is a way to do it?

I am a new member and I am not allowed to post link, it seems, so I will try to do that in the comments.

The file can be accessed from Google as follows (from the Climate Change Committee website) by searching: Deep-Decarbonisation Pathways for UK Industry (Element Energy))
