Unable to Install Prestashop v1.7.0.0 Alpha 4

[raliabdillah]

I am trying to install 1.7 Alpha 4, failed with this error message: An error occurred during installation...

You can use the links on the left column to go back to the previous steps, or restart the installation process by clicking here.

1. 1: SQL error on query Table '<MY_PREFIX>_access' already exists

 

Any suggestions?

You need to create clear database.

Yes, I start from clear database.

Its new install, not a migration process.

Looks like this procedure executed twice.

If it stop onece in database could be some tables, so check it.

Thanks Endriu107,

Solved by restart all process from the beginning.

Clear browser history, delete db and create db in install process (not before install) and start install from "www.my.server/install" NOT from "www.my.server/"

 

Unfortunately, can not pin point the real caused of my case. But it works.
