Try doing it over this way:

Copy TB files from the laptop

- launch TB on the laptop

- go to TB menu > Help > Troubleshooting Information

- click the Application Basics > Profile Folder 'Open Folder' button

- the profile folder will open

- navigate three levels up to the AppData\Roaming folder

- close TB

- copy the AppData\Roaming\Thunderbird folder to a flash drive

---

Paste the copied TB files to the PC

- open the AppData\Roaming folder like you did above

- delete the Thunderbird folder, or copy it somewhere if you want to save it

- replace it with the Thunderbird folder from the flash drive

- launch TB
