Hi,

 I am trying to install DotNetNuke 8.0 in Windows 10, but I every time I try I get the same error: SQL login failed:

  I am following the steps from this video (Chris Hammond helped a lot) but I fail when I install DNN:

1.  Unzip DNN8 zipped folder in C:\websites\dnndev.me
2. Open INETMGR and create a site called dnndev.me (Application pool now is dnndev.me), physical path: c:\websites\dnndev.me, host name: dnndev.me, start web site immediately: true.
3. Open folder settings C:\websites\dnndev.me > Security tab > Edit > Add > type "iis apppool\dnndev.me" (user doesn't exist). Video minute: 5:02
4. Open folder settings C:\websites\dnndev.me > Security tab > Edit > Network > Modify: true
5. Create a new Database "dnndev.me" in SQL Management Studio
6. Create a "New Login" and map it to the previous database as db_owner
7. Open browser > Go to dnndev.me > Configure installation and default site.

 So, do you have any ideas on this? Will be grateful all. Thank you very much.

I think that your problema is that de step 3 must be after step 6, you must to:

1. Create a new Database "dnndev.me" in SQL Management Studio
2. Create a "New Login" and map it to the previous database as db_owner

after step 3

3. Open folder settings C:\websites\dnndev.me > Security tab > Edit > Add > type "iis apppool\dnndev.me"

I guess this is where I am wrong, you mean for Windows User? SQL User?

I will try that.

You are everywhere! I am using local SQL Server, I was using Azure before but I was not able to update from DNN 7.4 to 8 so I changed to "local" everything.

Thank you all for your answers.
