Database connection Error in Stock Trader 6.1 setup

Question

I'm trying to install the Stock Trader 6.1 application locally on my laptop and I'm running into an error in the database connection section that I can't get past.

I have SQL Server 2014 Developer Edition installed, on Windows 10. I tried my initial install against a default instance, and that failed. I then read some other threads about how it works better with a named instance, so I created a named instance and tried that, but it didn't work. Finally, in desperation, I installed SQL 2014 Express Edition, thinking that maybe it had to be Express, but that didn't work either.

I can connect to all of these instances with both SQL Server Management Studio and with Visual Studio 2015's Server Explorer, but in setting up the Stock Trader app I get the below error.

Any help would be much appreciated.

Answer 1

I have subsequently installed SQL 2012 Developer edition, with a named instance and tried it against that, and that fails with the same error. I can't seem to find any installation log (at least not in AppData), either, that would give more details on the error.

Answer 2

Now I've created a VM with Windows Server 2012 and SQL 2014 Developer version. Same error. What's going on here?
