I have an old notebook from a previous computer that I had copied to a hard disk and then copied again to my new computer. The only issue is that I can't seem to open the notebook on the new computer. I had to install Python for the first time on the new computer, so I don't think it's a problem with an old version. The error also just says "Error loading notebook. Error" and nothing else.
I was going to try changing the browser as suggested here because my default browser in my old computer was Edge, but now it's Chrome. But I can't seem to find the exe file needed to do it as suggested in this link. I get to the Microsoft>Edge part of the navigation, but I don't find "Application", only "User data". Apologies in advance for any ignorance.
