bypass Installations Wizard

(I know there are already existing topics with older versions but i still face the problem)

I want to test a costomized 4.4 Version (with existing DB) first on the local IIS Windows 10  

After publishing i faced (as expected) the installation wizard. (I haven't executed it)

I placed the dataSettings and plugins json files at App_Data directory

i changed the default connectionstring (windows authentication)  used in Visual Studio:
"Data Source=WINFODESK\\SQLEXPRESS01;Initial Catalog=gemjewelsDb;Integrated Security=True;Persist Security Info=False"

with the connectionstring that IIS uses

"Server=WINFODESK\SQLEXPRESS01;Database=gemjewelsDb;User ID=sa;Password=●●●●"

but i recieve HTTP Error 500.30 - ASP.NET Core app failed to start "

Any idea?

Thanks!

Enable the log in the web.config to get more detailed error messages.

I recommend that you first go through the normal installation wizard with the plain (not customized) version of nopCommerce to verify that the system requirements are met - i.e. ASP.NET Core installed, folder permissions, DB access, etc.

thank you for your quick response

i removed the  2 jsons files from the App_Data. The installation with the customized version succeeded and a new DB was created!

I retried after creating a new Site on IIS with the datasettings file witch was created on the previous step (i changed ONLY  the DB Name to the existing one)  and i recieved ERR_CONNECTION_REFUSED !!!
(The SQL Server Instance is the same one)
"DataConnectionString": "Server=WINFODESK\\SQLEXPRESS01;Initial Catalog=gemjewelsDb;Persist Security Info=True;User ID=sa;Password=1234",

RE: " new Site on IIS" ... ERR_CONNECTION_REFUSED

I don't think that's due to DB.  Check IIS logs.

(also, try another browser; could be due to cookies and such)

Thank you so much for the speedy reply
I saw the logs
in IIS was nothing suspicious
In SQL SMS was  a message "parallel redo is shutdown for database...with worker pool size[4]"
The connection is established but collapsed immediately
Google says " because the databases aren't participating in an Availability Group"

If there is a datasetting file in App_Data the installation crashes.
It works only with creating a brand new Database File
When i try to install through the installation wizard inserting in Dialog the connectiongstring of  my existing DB, the istallation breaks and i recieve an "old" error:
"Sequence contains more than one element"

Cann anybody suggest me how to install nopcommerce without loosing my Work?
Must be a way!

You don't want to run the Installation Wizard...
Copy ALL these files from 4.30 folder to the 4.40 folder
\App_Data\  
  dataSettings.json
  plugins.json
  appsettings.json

This was the very fist thing i have done (see my first post)
The Problem was that in visual studio the ssl was enabled!
The setup crashed because all requests were false adressed (https:)
i wasted a lot of time searching for permission issues in SQL server and in IIS
Thanks!
