I am migrating Windows Live Mail with several accounts to a new PC. The export program from WLM failed to pick up all the messages, so I'm trying to use GFI Backup.

On the old PC with Vista I backed up WLM, then tried to open the job in GFI Backup 4.1 on Win 7 but this also failed with a declaration that tasks with plugins or registry access aren't possible (I didn't specify plugins or registry access).

Web based accounts such as Hotmail and Gmail have synced, but the others imported only a few ancient messages. I now have an incomplete, messy, WLM installation on the new PC.
