error during upgrade to latest version from 2.3.6

Hi all,
i need help. During the upgrade i get the following error:

JInstaller: :Install: SQL-Fehler Duplicate column name 'requestanswer'

Any idea what is going wrong?

Best regards

I search here in the forum and found:
Nach der Fehlermeldung bei update, schau bei Datenbank und reparieren drücken. Nachher nochmals installieren!

Thanks for the info. It had to run it 2 times and ignored a new error but then it worked.

Now i have to update my template..

many thanks
