I have installed Kartris using the platform installer.
I have changed the Application Pool to Framework 4.0.
I have added NetworkService Account with full access.
The error occurs after clicking "Next" in "Step 3 - Connection String" (browser shows "http://localhost/Kartris/Admin/Install.aspx").
The server name was entered as "localhost\sqlexpress" and that database name is "kartris1".
Here is the error I get:
START======================

AutoGenerate cannot be used in a cluster. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Does anyone know what is going on here? The solution online require editing web.config but I suspect I do not have to do this and I am doing something wrong! Thanks.
