Here is My error Message:
My System is Windows Server 2016 and as SQL-Server im using mssql server with there was an problem on my first installation but i got them with this Workaround:The installer detected a timeout
The installer has detected a timeout, you may try to refresh the page, which may lead to data corruption. We suggest that you either increase your timeout settings or try to use the CLI.
So now i think there will be some same problem but in the updated mssql.php the lines are fixed now.
Maybe someone has a working solution?
