If your talking about capture preferences.You can export all your presets and import them into the new laptop.
I would consider deleting the other profiles/presets first. Because you end up with a lot of duplicates. And there can be keyboard shortcut conflicts.Import presets is directly above Export. The file is .snagpresetsIf you want to transfer your .snag files from the library you can export them from the library as follows. Bear in mind,only .snag files are stored in the datastore. Saved captures are stored to wherever you saved them to. Pictures folder, Documents, etc.
As far as I know, that's about as close to making SnagIt look the same on your new computer as it gets. Unless some one else comes along with further tips?
