Object reference not set bug


#1

Hi there,

We’re really interested in using your product but would like to do some staging testing. However, during installation of the server, I get an ‘Object reference not set to an instance of an object.’ error in the following URL (right after table creation): coderr/installation/setup/basics/

Any idea what could cause this? I’ve tried running it on several Windows Server boxes (from 2012R2 to 2016) with the latest SQL Server (2017 express).

This is the full error page:

Server Error in ‘/coderr’ Application.

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.
