GrampsAIO uses Oracle Berkeley DB version 6.0.30 but MSYS2 have it at version 6.0.19 and most probably never update it to a newer version.
<br>Gramps will ask permission to downgrade database version at import of any family tree created with GrampsAIO bundle. To prevent that build right version of DB.
<br>Start ''msys2 shell'' and type:
pacman -U mingw-w64-x86_64-db-6.0.30-1-any.pkg.tar.xz
As db version is changed then we have to rebuild Python bindings for Oracle Berkeley DB
