Moving files from one cpu to another

I have a collection of personal finance files I keep in a 3 gb file I created using Veracrypt.
This has worked well on my old computer, but now I need to put it on a new one.
When I tried to look at the file, I get “object is not from a domain listed in the select location dialog and is therefore not valid.”
I don’t know what that means. I am also wondering if I should try some other forum, as this problem is not specific to Norton.
