So I will start over with a fresh installation of 7.57.

Thanx for helping!

Is there any way to proceed with the current installation?

There is an automatic migration from 0.7.56 to 0.7.57. If you start the
update process of 0.7.57 on a 0.7.56 database, it will write back the
0.7.57 format.

Other than that, 0.7.53 is over five years old, and I do not remember

it looks like there have no database changes happened since. It is
definitively untested, thus if you can then you should make a copy of
your database before applying. If not, you do not lose anything over
deleting it.
