Hello Pascal.
This can happen occasionnaly on Joomla installs, but J2Commerce should have been installed fine.
Usually, a refresh of the install page shows the install feedback messages that should have been seen.
Is J2Commerce installed now or is there any issue?
If it is not installed, can you edit the ticket and provide us with login credentials? Thanks!
Olivier.
