Hello,

I have version 7.0.2-5, but when I start with the command it does not
start, but on older version starts.

Can I somehow start the newest? When I check the DSM says only 7.whatever
is installed, all of others are not installed.

I tried to intall all versions and the deinstall all, finally reinstall
7.whatever but it finally started 4.1.9 again, even if I can only istall
4.4.4-49.

I am stuck. Again.

Thank you of you have an idea.
