Hello,

I just downloaded the latest version to do a fresh install.

But i get this error after i enter my database details and click next.

I did check the database, and i can see it created 2 tables.

does anyone know what this error could be, and how to fix.

```
Error
Received an error message.
URL: importDatabase
Message:

Please try to fix this error and restart the update.
Response
Slim Application Error
The application could not run because of the following error:

Details
Type: Error
Message: Class 'Symfony\Component\HttpKernel\Exception\HttpException' not found
File: /home/nginx/domains/store.rack/vendor/shopware/core/Framework/ShopwareHttpException.php
Line: 8

```

i have checked, and all the files are there.

this is running on CentOS 7 with NGINX,&nbsp;with all the correct PHP/SQL.

i am using&nbsp;Composer 2.0, if that is a cause of issues?

I had a fatal error:

PHP Fatal error: Class ‘Symfony\Component\PropertyAccess\Exception\RuntimeException’ not found in [/var/www/html/roadsofearth/vendor/symfony/property-access/Exception/UnexpectedTypeException.php](https://forum.shopware.com/discussion/26868/nach-erster-installation-komme-ich-nicht-ins-backend) [essays.agency](https://essays.agency/)

It stopped php script execution. There were many errors in error.logs.
