How to restore from backup for Sage 50 Pro 2018 on new computer?

SUGGESTED

So, my laptop got hacked, and I took it in to get cleaned out. It was taking forever for them to finish, so I bought a desktop in the meantime. I can't seem to be able to restore from backup on the new desktop. My laptop has Sage 50 Pro 2018 on it. I'm able to access all my data on my laptop, but when I try to restore from backup via my USB stick form the laptop to the desktop, it comes up with a message saying "the file cannot be restored on the selected directory because you do not have write permissions". I found a download on this site for Sage 50 Pro 2018 "Education Edition", it sounded like it might work, but I can't seem to make it happen... I'm pulling what's left of my hair out here, and when I called Sage, they were less than helpful.
