Can't transfer old Thunderbird data to new computer

I tried to transfer Thunderbird file from old computer to new computer but get "Profile cannot be loaded. It may be missing or inaccessable." when I start Thunderbird. The old TB file works on old computer and I am pretty sure I copied it and pasted it into the new location in place of the current Thunderbird file.

No, you made an error in placing it. here are the steps:

BACKUP

  1. ensure thunderbird is not running
  2. enter %appdata% in search window on task bar and press Enter key
  3. this should open windows file explorer in Appdata\roaming folder
  4. highlight the Thunderbird folder and copy to external media

RESTORE

  1. ensure thunderbird is installed and NOT running
  2. enter %appdata% in search window on task bar and press Enter key
  3. you should be in Appdata\roaming folder , copy&paste the exported Thunderbird folder there. This will prompt to overwrite an existing folder of same name. allow it
  4. start thunderbird and all should be there
